I have a 365 account with multiple domains. For simplicity's sake lets just use two, the one I made the account with and another I added to the account that I would like to make the the primary domain. Rebranding / not sure if the previous domain will be kept.
Is it easier to just make a new account with the second domain and migrate all my others there?
Or is there a way I can essentially "swap" the domain I want to be primary with the current main domain?
I hope this makes sense. Thanks.
Migrating everything over to a new tenant can get complicated very quickly. It will usually involve a third party software to get something like all Microsoft Teams messages, channels, and chats transferred successfully. I would recommend having your secondary domain added to your current tenant. Then, if I understand your question completely, it would be as easy as going to portal.azure.com > Active Directory > Custom Domain Names then making your new domain the primary. When you get multiple tenants involved, in my experience, creates more headaches than what they're worth.
Dr_Xunil answered my question in the comments. I didn't realize I could change the primary domain just like that. Thanks!
