Steps for Migration between Office 365 Tenants

The first step of tenant-to-tenant migration is preparing both tenants for migration by ensuring that all required accounts are set up correctly and that all user licenses have been assigned accordingly. This includes setting up service accounts with appropriate permissions on both sides as well as configuring mail routing rules if applicable. Additionally, you should also make sure your source environment has an adequate amount of storage space available for migrating data from one tenant to another before beginning any migrations processes.

The second step involves creating a custom mapping file that defines how users’ identities will migrate from one tenant to another using tenant to tenant migration. This ensures users retain their existing identity when they move over to their new environment without needing additional manual intervention or configuration changes during or after the actual move itself.

After these two preparatory stages are complete, you can move content between environments using Microsoft 365 migration tab manually via PowerShell scripts. Make sure that proper testing is conducted prior to executing large-scale moves so potential issues can be identified early on in order to avoid delays later down the line for the successful tenant to tenant migration.

Finally, once everything has been moved successfully it is important not to forget about cleanup tasks such as disabling old services/accounts no longer being used in order to prevent security risks arising due to incorrect configurations left behind after the completion of projects like these.
