I was a bit misleading, yes, just 3 DCs.

I’d do the upgrade by rpm.
I did find something in the samba wiki as I had time to google, which says the other way round; starting with a server that dose NOT hols a FSMO.
If you are updating multiple Samba Active Directory (AD) Domain Controllers (DC), the recommended order is:
Update one Samba AD DC that does not hold any flexible single master operations (FSMO) role.
So thats the way to go ?
And dose all DCs should be shut down at that time?
