Tenant to Tenant Migration because of Renaming the Tenant

We have to get rid of our Tenant Name due to aquisition. I know that there is no renaming functionality for a Tenant and the only way to do this is creating a new Tenant and migrate into the new one....

You can't sync to multiple tenants with the same AD Connect instance! You can Create another AD Connect installation and sync to a different tenant but not with the same objects!

I recommend:

Stop sync!

Uninstall ADconnect

Reinstall and sync to new tenant - Configure ADFS for the new tenant

Thanks Adam for quick Response,

regarding your post...

- what means not with the same objects, when i move to new tenant as example newtenant.onmicrosoft.com my guess was that i Change in on-prem AD the Users UPN to user@newtenant.onmicrosoft.com then start synchonization to new tenant

hi!
As long as the synchronization is stopped!
If you're gonna use the same custom domain in the new tenant, every object/user in the old tenant with that domain must be disconnected from that domain and then this has to be removed from the tenant
