Best Way to Start Your Office 365 Tenant to Tenant Migration

The first step in any Office 365 Tenant to Tenant Migration is to understand what’s moving. That includes email accounts, shared data, and settings. Make sure the destination tenant is ready and test everything in advance. Plan the migration during off-hours to avoid disrupting work. Communicate every step with your users.

For a smooth Office 365 Mailbox Migration, prepare by checking the size of each mailbox. Start with a few test users before migrating everyone. Use reliable tools that support large mailboxes and shared mailboxes. After the move, confirm that email delivery and calendars are working. Help users reconfigure Outlook if needed.

OneDrive for Business Migration is about more than just copying files. You need to make sure sharing permissions and file history are kept. Some users may have large folders or deep file structures—handle these with care. After the migration, ask users to check their files. Offer support guides or videos for common sync questions.
