Watch: Automated batch migration for Google mail overview

Check out this video and others on our YouTube channel .

You can migrate the following functionalities from Google Workspace to Microsoft 365 or Office 365:

Mail & rules

Calendar

Contacts

You can migrate batches of users from Google Workspace to Microsoft 365 allowing a migration project to be done in stages. This migration requires that you provision all of your users who will be migrated as mail-enabled users outside of the migration process. You must specify a list of users to migrate for each batch.

All procedures in this article assume that your Microsoft 365 domain is verified and that your TXT records have been set up. For more information, see Set up your domain (host-specific instructions) .

Google Workspace migration is not currently available for Microsoft 365 US Government GCC High or DoD.

Data type Limitations

Rules will be migrated and remain turned off by default. We advise users to verify the rules on Outlook before enabling them.

If you will be starting your migration batch with Exchange Online Powershell , as described later in this article, use the -ExcludeFolder parameter to prevent certain folders from being migrated. This reduces the amount of data in your migration, and the size of a user's new Exchange Online mailbox. You can identify folders you don't want to migrate by name, and you can also identify Gmail labels that apply to multiple messages in order to exclude those messages from the migration. For more information on using -ExcludeFolder , see New-MigrationBatch .

To skip the migration of Gmail filters, use the -SkipRules parameter to prevent the migration of Outlook rules. For more information on using -SkipRules , see New-MigrationBatch .
