Migrating from Google Workspace with Multiple Domains
FcoManigrasso Thanks! Just for clarification, when migrating emails over, it is possible to migrate from domain1.com (on GW) to domain2.com (on 365)?
Hi hewoods23,
Absolutely yes. You'll use a target delivery domain for the mail users for the migration task, ( usually a subdomain of your primary domain ), as described here: https://learn.microsoft.com/en-us/exchange/mailbox-migration/googleworkspace-migration-prerequisites#google-workspace-migration-prerequisites-in-exchange-online
It doesn't matter if you then, ( or before ), use domain1, 2 or 3 as the main one.
Mailboxes migration, O365 domains and EXO Primary SMTP are different things, ( related but not the same ). In fact, for the migration task, you could also migrate to the onmicrosoft.com mail users. ( I'm not saying you should do that, it's only an example to understand that you can migrate from domain1 to domain2 without issues ).
Hope this helps and wish you a good day... And good luck with your next migration 🙂
