What will happen after import hyper-v vm then join it to domain

We got a hyper-v image (winserver) and want to import the out server1 (hyper-v ruing on it). server1 as our domain machine.

Can we join the VM to domain after import it?

Any problem like file missing or setting lost in the VM after join doamin?

Because after join domain, VM is use account from AD. It is a new account. Maybe some fils local account will not found under new account?
