This article provides instructions on configuring a migration batch for migrating Microsoft 365 Groups between Microsoft 365 tenants. The setup process outlined here focuses on migrating mail, calendar and drive items.
Before proceeding, ensure you have completed the steps in the Microsoft 365 to Microsoft 365 Migration Guide to set up your migration project and added your group migration batch.
Adding Items to Migrate
When adding items to migrate Microsoft 365 groups to corresponding accounts at the destination, follow the format below:
- Export Type: Microsoft 365 group
- Export Name: Source group email address
- Import Type: Microsoft 365 group
- Import Name: Destination group email address
- Given Name: Destination group display name
- Family Name: Not required
- Documents Path: Not required
- Documents Destination Path: Not required
For each Microsoft 365 group entry, select the specific items you wish to migrate. Make sure the 'Migrate' option is enabled for all users included in the migration.
General Settings
In the General Settings section, ensure all domain mappings are configured correctly to facilitate replacing the source domain with the destination domain during the migration.
You can also apply date range filters for various data types to migrate information within a specific timeframe. Specify the date ranges you wish to include.
Source Settings
For a standard Microsoft 365 group to Microsoft 365 group migration, it is recommended to keep most of the source settings at their default values. However, some settings may need adjustment:
-
SharePoint Online -> Default document library name: If you are migrating files, modify this setting to match the language used in your source tenant.
Destination Settings
Depending on your migration plan, you may need to modify several settings in this section:
-
SharePoint Online -> Migrate previous document versions: Enable this option to migrate previous versions of the groups documents. Enabling this feature allows you to select the number of versions to migrate but will significantly increase migration run times.
- SharePoint Online -> Maximum number of previous document versions: Select the number of versions you plan to migrate.
-
SharePoint Online -> Include document metadata: Enable this to migrate both standard and custom document metadata, including text, boolean, number, and datetime fields.
- SharePoint Online -> Default document library name: If you are migrating files, modify this setting to match the language used in your source tenant.
Advanced Settings
For a straightforward Microsoft 365 group to Microsoft 365 group migration, most advanced settings can remain at their default values. However, consider the following:
-
Address Replacement: It is highly recommended to upload an address replacement CSV that maps source users, aliases and groups to the destination. For more information, please refer to the Address Replacements article.
Migration Process
The migration process will vary depending on your project's specific approach. Generally, it is advisable to start with a bulk migration and perform delta migrations closer to the final migration cutover date.
