I need help with migration

Hello

I need to migrate our account to a wider business due to a merger.

In general, I need to change the domain name while keeping my email history without losing any data.

On top, I need to ensure after that after the change the extensions of our emails from (i.e @ abc.com to @ abd.com) to have access to the emails which are still being sent to @ abc.com, for example being automatically forwarded to the new email addresses.

    Add the new domain in Microsoft 365 Admin Center, make it primary, 
    and keep the old domain as a secondary alias. This way, all history stays intact 
    and old emails continue to arrive without issues.

    All that you mention is possible. Becasue you haven't mentioned about either the source or target environments (or even if you in fact need to do a migration or just need to change your primary email address), I'd guess you're not that technical, so I'd recommend looking around for a 3rd party that can help you do the work. Perhaps the buinsess you are merging with has the technical knowledge to help you do the work.
