1. Discover accounts in ODM
2. Match the accounts
3. Migrate the mailbox including calendar
4. Cutover the domain to the target tenant
5. Updated the target user(s) to have the UPN and Primary email of the domain moved from the source tenant
   Note: the user name part of the Email address and UPN doesn't need to match for this to work.
6. Run a new Discover task in ODM so that the user now has the onmicosoft UPN for source
7. Run a Match task so that the target UPN is updated to the domain moved from source
8. Run the Meeting Link task
9. Have a user verify new meeting links are updated and the organizer can start future meetings using the link in the calendar appointment 

Note: Perform these steps on a single mailbox and confirm the meeting links have been updated before migrating all users.
