Cross-tenant SharePoint migration FAQs

Premigration FAQs

Question: Can a SharePoint account have any content in the target tenant before migration?
Answer: No. The tool doesn't support Merge functionality with existing content. The user being migrated must not have a preexisting SharePoint on the target tenant.

Question: Can users be precreated on the target tenant?
Answer: Yes, all Users/Groups that are identified for migration should be precreated on the target tenant and appropriate licenses assigned before staring any migrations. Also:

• SharePoint site creation should be restricted in the target tenant to prevent users creating SharePoint sites.
• The migration fails if a SharePoint site already exists for the user on the target tenant.
• You can't overwrite an existing site.
• SharePoint sites should NOT be created before OR during a migration.

Question: Can my SharePoint accounts be in Read-only mode before starting any cross-tenant migrations?
Answer: No. Before starting any migration, you need to ensure that your Source SharePoint accounts are NOT set to Read-Only, otherwise the migration fails.

Question: Can my SharePoint accounts be in Read-only mode before starting any cross-tenant migrations?
Answer: No, before starting any migrations, ensure that your source SharePoint accounts are NOT set to Read-only. Otherwise, the migration fails.

Question: Does the tool support GCC and GCC-High tenants?
Answer: We don't currently support government environments (GCC & GCC-High) but we plan to support them in the future.

Question: Are SharePoint accounts with Customer Key Encryption supported for migration?
Answer: No. We do NOT support migration if the source tenant has Service encryption with Microsoft Purview Customer Key enabled.

Question: What do I need to consider for migrating sites between Multi-Geo tenants?
Answer: If you're a SharePoint Multi-Geo or MNC customer, you must treat each geography as a separate tenant and supply the correct geography-specific URLs throughout the process. You must also establish trust between each geography involved in your migration project.

Post-migration FAQs

Question: What happens to permissions on SharePoint content?
Answer: Users with permissions to SharePoint content continue to have access to their content upon completion on the new target tenant, if those users/groups were included as part of the Identity Map and mapped accordingly.

Question: What happens to sharing links?
Answer: After the SharePoint cross-tenant migration, existing shared links for files that were migrated automatically redirect to the new target location.

Question: How are shared files handled?
Selecting a sharing link to the old location redirects to the new location. The original/source tenant is deprovisioned or the admin can remove it on a site-by-site basis.

Question: Do external Shared Files still work?
Answer: As part of the migration process, Admins must precreate the appropriate users on the destination tenant, including guest/external users, and provide the tool with an "Identity Map." The identify map tells us how to adjust file/site ownership and permissions.

Question: If a file is shared in a Teams chat, are those files still accessible after migration?
Answer: See the question above. The identity map informs how files are shared. If a user selects the link, it attempts to redirect to the new location. The file is accessible as long as the user has permissions to access the file on the destination.
