Microsoft 365 Tenant to Tenant Migration - Using the Free Native Tools inside M365. ** Update ** - This is a re-edited version of the original M365 T2T Native Tool video that was removed because it contained PII (Personal Identifiable Information). All the email address data of the dummy/test users has now been blurred out. If you need any help with some of the processes because of the blurred nature of some of the information then please reach out to me via website. Here I migrate Microsoft 365 Exchange Online from one tenant to another using only the free tools that are now a part of M365. There is no paid toolset in use here at all. I take you through the setup and configuration needed to perform the migration, then perform the migration itself, showing every step along with the way. The main points that are covered in the video are; * Setup of the Security Group needed to scope the migration * Configuration of the App Registrations required in the Tenants to allow the connections * Organization Relationship setup * Creation of Mail Users to prepare the target * Stamping of the objects with the Exchange GUID's to bind the identities * Creation of the migration batches * Syncing and Completing the migration batches * Forwarding and Mail Routing for both source/target accounts pre/post migration * Moving the underlying domain name from one tenant to another * Adding aliases to the new tenant As you can see, the entire migration is covered and during the process I show all the processes needed plus any errors that pop up along the way. Providing the fixes where necessary but essentially keeping it as 'real-world' as possible. All of the PowerShell commands used in the video are laid out in the article on the website, so check that out at Please remember to subscribe to the channel. You can use this link to do that. Thank you for watching, commenting, liking and subscribing. I hope this helps in choosing how best to migrate Microsoft 365. Mark - The Cloud Geezer
