- Jun 06, 2018Hi, we do it in this way normally for our customers: - Define migration-date (day x)
- old-tenant: old.onmicrosoft.com, new tenant: new.onmicrosoft.com, default-domain: contoso.com (set up on old.onmicrosoft.com)
- Setup new mailboxes on new.onmicrosoft.com
- Pre-migrate content older then 90days from old.onmicrosoft.com to new.onmicrosoft.com (by migrationwiz.com)
- set TTL of contoso.com to 5min (day x -72h)
- on day x, remove contoso.com from old.onmicrosoft.com (by script remove it from everywhere (mailboxes, alias, groups etc.)
- add domain contoso.com to new.onmicrosoft.com
- make the domain verification
- add by script the domain to mailboxes, alias, groups etc.
- Finalize the migration (full-migration) trough migrationwiz.com to get the rest of the content (newer tan the 90days of the past)
- Attach security permissions of mailboxes and so on
 I hope these will help. Regards, Matthias

- AnonymousJun 06, 2018Hi Matthias and thank you for your answer. What is the reason that you use BitTitan for synkronizing , instead of just using migration option in office 365 Exchange Administration ? Greeting Jorgen.
