From memory, there were problems upgrading/joining such old versions of
Samba, these were addressed around Samba 4.8.0 . there have also been
major changes since 4.8.0 , so doing it in two stages might be the best
idea, of course making a major jump to the latest version might work,
but I would test it first.
