Domain Transfer to IONOS: Moving Emails and Folders to an IONOS Email Account

This article explains how to move the emails and folders of an email account with the IONOS Email Migration Service powered by audriga as part of a domain transfer from another provider.

Depending on the respective provider and product, additional data such as contacts or calendar entries may be able to be transferred as part of the email migration as well.

You won't need to install any software to move your email and folders. The IONOS Email Migration Service powered by audriga connects to the accounts using the same protocols as a normal email program and moves your emails from the previous provider to IONOS.

Notes
  • Only data that is stored on the server(s) of your email provider can be transferred. This service is not able to migrate data saved exclusively on your end devices.

  • When you move a domain, only the domain itself is moved during the transfer process. Associated email addresses are not moved.

To migrate an email account, follow these steps:

  • Set up a destination (receiving) mailbox for each source (sending) mailbox. You can use a subdomain or another domain for this purpose if desired. As long as this is in the same contract receiving the domain in the domain transfer process, you will easily be able to change the domain/subdomain to the correct domain later.

  • Check how much disk space the source mailbox is using. This must not exceed the size of the newly created target mailbox. Please note the existing limitations and notes listed here:

  • Move the emails and folders using the IONOS Email Migration Service powered by audriga. Please note the steps described in the section Starting the Email Migration.

  • Check that all of the emails have been moved.

  • Perform a delta migration to move emails that have arrived in the source mailbox after the email migration is complete.

  • Move the domain to the desired target contract.

  • Rename the target mailbox in your Control Panel. To learn how to rename your mailbox, see the article Changing Your Email Address.

Starting the Email Migration

  • To open the web app for the IONOS Email Migration Service powered by audriga, click here: https://emailmigration.ionos.com/.

  • Read and accept the terms of use and the privacy policy.

  • Click Proceed.

  • In the Select Current Provider field, select your previous provider. If your previous provider is not displayed in the list, search for the provider.

    If the provider is still not found, select the entry Add missing provider or server. Then select the protocol used in the Protocol field and specify the email server of your previous provider. This is listed in the instructions provided by your current provider for configuring email programs (such as Outlook or Thunderbird). Examples: imap.gmail.com, mail.gmx.net

  • Select the appropriate IONOS email product in the Select new provider field.

  • In the Additional information section, enter the email address where you can receive status messages during the migration process.

  • Specify whether you are a private or a business customer.

Note

If you are a business customer, you will be offered a standard contract for order data processing.

  • Click Proceed.

  • Enter the login details for your source and destination mailboxes.

  • To check whether the login is possible, click Check.

  • If the login is possible, click on Confirm, and the estimated moving time will be displayed.

  • In the Earliest start of migration section, specify the desired start time.

  • Click Proceed and the summary of the migration will be displayed.

  • Click Start Migration.

A status page will then be displayed where you can follow the progress of the migration. In certain cases, it can take some time before your move starts and the data is copied. Depending on the amount of data being migrated, the entire process can take up to several hours.

You can close the status page during the migration. It will continue in the background automatically.

After the setup, as well as at the start and end of the move, a notification email will be sent to the email address you provided. These notification emails contain a link with which you can view the status page again if desired.

Starting a Delta Migration

After you have completed the email migration, you can start a Delta (change) Migration once on the status page. This will copy emails that arrived in the source mailbox after the email migration finished.
