If I remember correctly, Ubuntu 18.04 has Samba 4.7.6 (all be it with 
security updates and anything else they backported)

Ubuntu 22.04 gets you 4.15.13 (if I understand correctly)

If you really want to get to a Samba supported version (and you should), 
jump ship to Debian 11 and use Samba from backports, which will get you 
4.17.7

Which ever way you go, I wouldn't want to upgrade Samba in the way that 
you are proposing, there is just too much that can go wrong. I would 
join a new computer as a DC, then demote the old one.
