Yes, set up a new DC with your new OS and join this to the domain, once
up and running, transfer the seven (yes, there are 7) FSMO roles to the
new DC. Once everything is running ok, turn off the old DC and remove
*all* mention of it from the domain.
Not easy, but it can be done.
Of course it would have been a lot easier if you hadn't used the samba
version from git. It would also be a lot better if people read and
accepted what is written on the wiki.
