Email migration tool

Email migration you run yourself, without stopping your team

With our tool, you bring your company email over yourself from the admin panel: buy the migration GB you need at the checkout, upload a spreadsheet, see what will be copied and follow the copy live. Addresses stay the same, and your team keeps working in the current email until the switch.

R$ 2.00 per GB migrated from the source, paid once, with no monthly fee. You buy at the checkout yourself, without talking to anyone. Nothing is deleted at the old provider.

Two ways to migrate your company's email

In both, messages are copied from the old provider before the switch, and nothing is deleted there. The difference is who leads: you, through the panel, or our team, with you.

How to migrate emails with the tool, in six steps

From the old provider to the new mailbox, in the panel, with nothing to install. The full step-by-step guide, with the server table for the most common providers, is in the step-by-step migration guide and in the panel manual.

  1. Estimate the GB of the accounts and create the destination mailboxes

    Add up the size of the mailboxes on the old provider, no need to be precise: the admin panel preview measures each account for real. In the admin panel, create the mailboxes that will receive the emails, with the same addresses you have today. The migration copies into mailboxes that already exist.

  2. You buy the migration GB at the checkout yourself

    At the lua.email checkout, you buy the expected migration GB yourself, without needing to talk to anyone (R$ 2.00 per GB migrated from the source, paid once, no monthly fee). They become a balance in the admin panel, to use in the tool. If you buy again later, the new GB are added to the balance.

  3. Upload the spreadsheet and see what will be copied

    One row per account: the email and password at the old provider, the IMAP server, the port and the destination mailbox. You can build it in Excel or Google Sheets and save it as CSV. Download the template or see how to build it, with a ready example. The preview signs in to each old account and shows the login, the messages, the size, the available GB, what will be copied and what is left out.

  4. Confirm and follow the copy live

    Accounts go in spreadsheet order, until the migration GB run out. The copy starts in moments and the screen shows live the folder being copied, the messages already copied, the speed and the time remaining. You can close the page: the copy keeps going on the server.

  5. After the MX switch, sync again

    After the domain moves to lua.email, click Sync again on the finished accounts. Only what arrived at the old provider since the previous copy comes over, for up to 7 days after the first complete copy. What comes in is taken from the migration GB balance.

  6. Need more GB? Buy and copy the rest

    The accounts left out stay on record in the task, with nothing deleted. Buy more migration GB at the checkout and click Copy the accounts left out: they go back into the queue and use the new balance.

Follow the copy live, no guessing

A large mailbox can take from a few minutes to a few hours to copy. So you are never left wondering, the migration screen has a panel called "What is happening now", which tells you in plain language what the panel is doing on each account. It refreshes by itself every 5 seconds.

  • Connecting and measuring.First the panel signs in to the account at the old provider and measures the folders. You read "Connected to the source server" and "5 folders found at the source".
  • Copying a folder.You see, for example, "Copying folder INBOX: 117 of 200 messages (58%), 104.9 MB copied", and the message and data bars for each account move along with it.
  • Speed and time left.For each account being copied, the screen shows the speed and an estimate of the time left. It is an estimate from the copy program itself and can change along the way.
  • Folder and account finished.You see "Folder Sent done: 24 messages copied" and, at the end, "Account done: 210 messages, 267.0 MB in 28 s".
  • Something went wrong.The screen gives the reason, such as a refused password or a server that did not answer, and you fix it and retry without duplicating anything. You can filter the log by account.
Halfway through the copy: one account finished, one copying and two queued, with the live log (real screen, fictional data).

Did email arrive after the MX switch? Sync again

The MX is the domain record that says where new email should go. Until DNS updates, and sometimes for a few hours after, a message can still reach the old provider. The Sync again button fetches only those messages and puts them in the lua.email mailboxes.

Job after Sync again: the log shows the incremental sync with 6 new messages and 4.1 KB, and the account total adds up both copies
After syncing: only the 6 new messages were copied, and the account total adds up both passes (real screen, fictional data).
  • When it appears.On each finished account, for 7 days after the first complete copy. Next to the button, the screen shows how long it is valid, for example "Available until 11/13 20:29".
  • What to do.Click Sync again on the account and confirm. The account goes back to the queue, and the log shows "Incremental sync: 6 new messages, 4.1 KB".
  • What it does not do.It does not repeat what was already copied, it does not delete anything at the old provider, and it does not extend the 7 days.
  • How much it costs.It is not charged again: what comes in this pass is taken from the balance of the migration GB you bought. With no balance, the button warns you and you buy more migration GB.
  • After the 7 days.The old provider password, which is kept encrypted only during that period, is deleted and the button no longer appears. If you need one more copy, talk to our team.
Sync again confirmation window: it copies only what arrived in the source mailbox after the last copy, what was already copied is not repeated, with the Cancel and Sync buttons
The confirmation explains what will happen before you continue. What comes in this pass is taken from the balance (real screen, fictional data).

The migration GB become a balance, and the preview shows what will be copied

You buy the migration GB once, at the lua.email checkout: R$ 2.00 per GB migrated from the source, no monthly fee and no renewal. They appear in the admin panel as a balance. The copy respects that balance, and buying again adds to what already exists. When there are migration GB bought, the admin panel home shows an "Email migration" card with the GB bought, the GB already used, the balance and the link to the tool.

  • Before you start.The preview shows the migration GB you bought, the available balance, what will be copied and what is left out, with how much is missing to migrate everything and the way to buy more.
  • Accounts in order.Accounts go in spreadsheet order until the migration GB run out. If one exceeds the balance, it is left out and the next one, if smaller, can still be copied.
  • An account failed.Trying again picks up where it stopped, without duplicating what already arrived.
  • Synced again.What comes in again is taken from the balance. Did 6 new messages arrive? Only their size is deducted.
  • Subscribed to more.Click Copy the accounts left out: the accounts that stayed out go back into the queue and use the new balance. The old provider's password is kept for 7 days, and after that you upload the spreadsheet again.

What gets migrated

The copy brings each account's entire mailbox, just as it was. Contacts and calendar come by file, or with our team, when the provider allows it. Nothing is deleted at the old provider.

WhatHow it reaches lua.email
Messages from all folders✓ Comes in the copy. Inbox, sent, archived and the folders your team created, with attachments.
Folders and subfolders✓ Comes in the copy. With the same names. Gmail labels arrive as folders, and a message with several labels may go to more than one folder (and add more GB).
Read, unread and flagged✓ Comes in the copy. Each message arrives as it was.
Date of each message✓ Comes in the copy. The original date, not the date of the copy.
ContactsBy file or by hand. Export as vCard or CSV from the old provider and import into the webmail. With our team, on request, when the provider allows it.
CalendarBy file or by hand. Export as .ics from the old provider and import into the webmail calendar. With our team, on request, when the provider allows it.
Filters, signature and auto-replyBy file or by hand. Recreate them in the webmail: the webmail manual has the step by step.

Where you can migrate email from

From any provider that offers IMAP access, which is the case for most. For Microsoft 365 and Outlook.com, the migration is done by our team.

Coming fromHow to migrate
Gmail and Google WorkspaceWith the tool, at imap.gmail.com, port 993. IMAP must be turned on in the account. With two-step verification, use a Google app password. Messages with several labels may be copied to more than one folder, increasing the volume and using more of the migration GB: talk to us to review it beforehand.
Microsoft 365 and Outlook.comWith our team. These accounts use a different type of authentication that the admin panel tool does not support yet. Our team does the migration and schedules the date and the steps with you.
Locaweb, HostGator, KingHost, UOL Host, Hostinger and other hosting providersWith the tool, using the hosting provider's IMAP. The address is in the provider's panel or in the Outlook instructions. It is usually imap.yourdomain.com or mail.yourdomain.com.
Unifique, HostGator, GoDaddy and other providers with cPanelWith the tool, on the account's cPanel server. It appears in cPanel, under Email Accounts, Connect Devices (at Unifique, something like cpanel05.unifique.cloud), port 993 with SSL. The addresses stay the same.
Your own server, Plesk or ZimbraWith the tool, if the server answers IMAP over the internet. Port 993 with SSL or 143 with STARTTLS.
Any other provider with IMAPWith the tool. The preview tests the login of each account before copying. If it won't open, our team looks at the case with you.

Keeping part of the team on Google Workspace or Microsoft 365? With lua Bridge, the two coexist on the same domain. To compare costs, see the price comparison.

No pause in receiving email during the switch

The old email keeps working until the end. The MX switch, which makes new messages arrive at lua.email, is the last step, on the agreed day.

  • The addresses stay the same.Mailboxes are created at lua.email with today's addresses. Customers and suppliers don't need to know about the switch.
  • A message that arrives during the switch.In the hours after the MX switch, a message or two can still land at the old provider while DNS updates. Sync again brings those messages over, for up to 7 days after the first copy.
  • Outlook and phones set themselves up automatically.The email address and password are enough, with the Autodiscover and the domain's autodiscover and autoconfig addresses in the DNS (two A records, with the value shown in the panel). The panel shows each record ready to copy and checks that it came out right. See email with your own domain and email on your phone.
  • The first day at lua.email.The team signs in to the webmail with everything that came from the old provider, and lua Colabora (files, documents and chat) already comes with the plan.

Calculator: how many migration GB to buy and how much it costs

Enter how many mailboxes and the average size of each, or the size mailbox by mailbox. The calculator adds them up, rounds to whole GB and shows the total: GB × R$ 2.00, migrated from the source, paid once.

Mailboxes0
Total size at the source0 GB
Migration GB to buy (rounded up)0 GB
Price per GB migrated from the sourceR$ 2.00
Total, paid onceR$ 0.00

You do not need to get it right the first time. If you run short of GB in the middle of the migration, buy more at any time at the checkout. The new GB are added to the balance, and the accounts left out are copied with one click, in Copy the accounts left out.

Where to see the mailbox sizes: the admin panel preview measures each account at the old provider, for free, before you buy. If you estimate by hand, round up and add a small margin, because attachments and folders can add up to a bit more than it seems. lua.email mailboxes have their own price table, starting at R$ 8.90 per mailbox.

What is different about our migration tool

Whoever manages the email does it in the admin panel and sees, before starting, what will be copied with the migration GB. No technician, no program to install.

The administrator does it, no technician needed

The company administrator, the reseller or the IT partner runs the migration in the panel, with a spreadsheet. No program to install and no command line.

What will be copied shows up before you start

The preview signs in to each old account and shows the size, the available GB, what will be copied and what is left out, before any copy. You confirm knowing the result.

You buy only the migration GB you need

R$ 2.00 per GB migrated from the source, paid once, no monthly fee. Short? Buy more migration GB, which are added to the balance, and copy the accounts left out.

Errors show in the preview, not halfway through the copy

A wrong password, a wrong server, a repeated or incomplete row and a destination mailbox that isn't yours show up beforehand, with a note of which row it was.

Folders and flags as they were

Folders, subfolders, read and flagged messages and the original dates arrive intact. Nothing is deleted at the old provider.

Repeating doesn't duplicate

An account failed? Retrying continues where it stopped. After the MX switch, Sync again brings over only what is new.

You see what is happening

The plain-language log shows the folder, the messages copied, the speed and the time left for each account, without having to ask anyone for an update.

Sync again does not charge a second time

What comes in after the MX switch is taken from the balance you already subscribed to, with no new charge while there is balance.

Prefer to have our team do the migration?

Our support team plans, migrates and checks with you, in stages, without your team having to stop using email. It is charged by the hour, with the price on request, and we agree on the timeline after looking at your case: how many mailboxes, how much email and where it comes from.

  • PlanningYou tell us where the email is, how many mailboxes there are and who uses what (aliases, groups, shared mailboxes). We build the plan and agree on the day of the switch.
  • Mailboxes and copyThe team creates the mailboxes with the same addresses, the aliases and the groups, and copies the messages with the migration tool while you keep using the old email.
  • Checking with youBefore the switch, we check with you what arrived in each account: messages, size and the accounts that had errors.
  • MX switch and final syncOn the agreed day, the domain moves to lua.email (MX, SPF, DKIM and DMARC), and a final sync brings over whatever still reached the old provider.
  • Contacts and calendarOn request: we migrate them when the old provider allows some kind of access to them. If not, we help bring them over by file.
  • After the switchWe help set up phones and Outlook and stay close during the first days for your team's questions.

What we need from you: the list of mailboxes and who uses each one, access to the accounts at the old provider (or each person gives their password on the day) and access to the domain's DNS or the contact of whoever manages it. Resellers and IT partners use the same tool to migrate the customers they bring.

Questions about email migration

How do I migrate email from one provider to another without losing messages?

Copy the messages before you move the domain, and copy again afterwards. With lua.email, the first copy happens while your team still uses the old email. On the agreed day, the domain moves to lua.email (the MX switch) and the Sync again button brings over whatever still reached the old provider. You can do it with our tool, in the panel, or ask our team to do it with you.

How much does email migration cost?

With the admin panel tool, R$ 2.00 per GB migrated from the source, paid once. You buy the expected migration GB at the lua.email checkout, and they become a balance in the admin panel. The preview shows what will be copied with those GB before you start. If you sync again after the MX switch, what comes in is taken from the balance. Short? Buy more migration GB, which are added to the balance, and copy the accounts left out. Done by our support team, the migration is billed by the hour, with the price on request.

How many migration GB should I buy?

Estimate the size of the mailboxes at the old provider and buy that many migration GB at the lua.email checkout (R$ 2.00 per GB migrated from the source, paid once). The admin panel preview measures each account for real and shows what will be copied. If you run short, just buy more, and it is added to the balance.

What if the accounts exceed the migration GB balance?

Accounts go in spreadsheet order until the migration GB run out. The accounts left out stay on record in the task, with their size and how much is missing, and nothing is deleted. Buy more migration GB at the checkout and click Copy the accounts left out: they go back into the queue and use the new balance.

Will I be without email during the migration?

No. Your team keeps using the old email while the first copy runs. Email only moves on the day of the MX switch, and Sync again brings over what reached the old provider in the following hours.

How do I migrate from Gmail or Google Workspace?

With the tool, using the server imap.gmail.com on port 993. IMAP must be turned on in the account and, if it has two-step verification, use a Google app password instead of the regular password. Review the case first: Gmail labels arrive as folders, and a message with several labels may be copied to more than one folder, which increases the volume (GB) and uses more of the migration GB. The preview shows the size before you start, and we recommend talking to our team to review your Gmail or Google Workspace account before migrating.

Can I migrate from Microsoft 365 or Outlook.com?

Yes, with our team. These accounts use a different type of authentication that the admin panel tool does not support yet, so the migration from Microsoft 365 (formerly Office 365) and Outlook.com is done by our team. Contact us to schedule the date and plan the steps.

How do I migrate from Locaweb, HostGator, KingHost or a server with cPanel?

With the tool, using the hosting provider's IMAP address, which appears in the provider's panel or in the instructions for setting up Outlook. It is almost always port 993 with SSL. The preview tests the login of each account before any copy.

Who does the migration, me or you?

You choose. With the tool, the company administrator, the reseller or the IT partner does it in the panel, with a spreadsheet. Or our team plans, migrates and checks with you.

How long does it take?

It depends on how many accounts there are and how much email each one has. With the tool, the copy starts within moments and the screen shows live the folder, the messages copied, the speed and an estimate of the time left. With our team, we agree on dates after looking at your case.

Do contacts and calendar come along?

The copy brings messages and folders. With the tool, contacts and calendar come by file: export contacts as vCard or CSV and the calendar as .ics from the old provider, and import them into the lua.email webmail. With our team, migrating contacts and calendar is on request: we do it when the old provider allows some access to them.

Do I need the password of each old account?

Yes, the email address and password of each account at the old provider. If someone does not want to share their password, they can change it to a temporary one just for the migration. The password is kept encrypted and is deleted when the 7-day Sync again period ends.

What about email that arrives after the MX switch?

Until DNS updates, and sometimes for a few hours after, a message can still reach the old provider. Each finished account in the job has a Sync again button, which copies only what arrived since the last copy, without repeating anything and without deleting anything at the old provider.

For how long can I sync again?

For 7 days after the first complete copy of each account. The screen shows the deadline next to the button, and syncing again does not extend it. After that, the old provider password is deleted and the button no longer appears.

Does Sync again charge a second time?

No. Sync again does not create a new charge: what comes in this pass is taken from the balance of the migration GB you bought, paid once at R$ 2.00 per GB. With no balance, just buy more migration GB.

Do I have to stay on the page during the copy?

No. The copy runs on the server. When you return to the job screen, the "What is happening now" panel shows the log, each account's bars and what has already finished.

Do the email addresses change?

No. Mailboxes are created at lua.email with the same addresses you have today. People who write to your company won't notice the change.

What if an account fails?

The account row shows the reason, such as a rejected password or a server that did not respond. Fix it and click Try again on the ones that failed: the copy picks up where it stopped, without duplicating what already arrived. An account that failed does not use the balance beyond what was already copied.

Is there a size limit?

The limit is the space of the destination mailbox. If the quota runs out in the middle of the copy, the account stops with that notice: increase the mailbox space and try again.

How do I request the migration?

Not a customer yet? Talk to sales on WhatsApp +55 47 99276-7511. Already a customer? Write to suporte@lua.email. With the tool, whoever administers the email starts directly in the panel, under Support, Email Migration.

Do I need to reconfigure phones and Outlook?

Yes, once, with the new server. With the domain's Autodiscover and automatic email setup ready, Outlook and phones find the server with just the email address and password. Our team helps whoever needs it.

Want to bring your company's email over?
