Hey everyone! We've successfully completed our migration from one MS365 tenant to another using BitTitan. Now, I'm wondering about the next steps regarding our domain. Once we move the domain to the new tenant, will we still be able to log into the old tenant, or do we need to do something else first?

You can still log into the old tenant with your onmicrosoft.com addresses after deleting the domain. Just make sure everything is set up correctly before making any changes!
Also, remember to disable the user accounts on the old tenant. If you don’t, their emails will still use the old domain, which could cause confusion. I learned that the hard way!
