You can continue to upgrade the distro and continue to compile Samba if
you wish. However, you could demote the DC, remove your self compiled
Samba, upgrade the distro and then rejoin as a DC. Or you could just
demote the existing DC, shut the computer down and then create a new DC
using the same hostname and IP.

What I wouldn't do is to upgrade the existing DC and try and
upgrade/install Samba unless your self compiled Samba has the parts of
Samba in the same places as where Debian packages place them.
