You will not be any worse off trying the commands, so give it a try.
I am not 100% sure the bug is your problem, but it sounds likely.

No, the easiest way would be to set up Samba 4.7.x in a VM and join
this to the domain. If this works, I would transfer the FSMO roles to
this VM and then demote the other DC's. You could could then reinstall
Samba 4.7.x on these and rejoin them to the domain, then upgrade each
to 4.8.x, restart Samba on each. Once all your old DC's are running
4.8.x correctly, you could then transfer the FSMO roles, then demote and
remove the VM.

I would also suggest you get good backups before doing anything.
