I've managed to successfully migrate a samba-AD to a windows-AD ... in a
test environment not yet in production.
I suggest you to start reading this:
My samba version is 4.15.13
The steps I've followed are:
- prepare samba
- add win2008 to the domain
- copy sysvol
- demote samba DC (the one without FSMO roles)
- transfer FSMO roles from samba to win2008
- demote the other samba DC
- add win2016 to the domain
- copy sysvol
- transfer the FSMO roles
- demote win2008
- add win2022
