Alibaba Mail supports data migration between different domain names by email migration.
Important
You can only have one email service for the same domain name in the Alibaba Mail system. For example, if example.xxx already owns an Alibaba Mail standard edition, you can no longer use example.xxx to apply for an advanced edition of Alibaba Mail.
For more information about how to configure email migration, please check Email Migration.
If you need to save the original email to the local computer, you can set the client to receive the emails from the original email service and save it to the local computer for backup. For more information, please check Client Configuration.
