#M365AMA How do I reroute mail through the right tenant post-migration?

“I have a customer that we're migrating Microsoft tenants because currently they have exchange online through a marketing company that is hosting all of their customers in the same tenant. As such, I know I'm going to have to do .pst exports to move the mail. I'm not worried about that.  I'm mostly concerned about how I'm going to reroute mail through the correct microsoft tenant. Is it as simple as adding and verifying the domain in the new tenant and ensuring DNS records are correct? DNS hosting will remain Network Solutions. I'm just trying to avoid potential mail routing issues."
