I agree, the problem is that the old server also worked as a file server,
now that I have the file server separated from the new ad-dc at any time
I'll demote the old server.

I wonder if to do:
  samba-tool fsmo transfer --role=all -UAdministrator

Is it the same as doing it with Rsync or if it is better.

I haven't searched for information on how to remove the old server yet, I
don't know if it's just disconnecting it or if I should run some command on
the new DC or the old one.

If you have any information on this it would be of great help.
