    Hi, 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.
