In thise case, epoch is just an extra RPM tag used to enforce versioning, 
nothing to do with time.  You could also rename the package instead, but 
the samba package already uses the epoch tag anyway (set differently for 
RHEL and Fedora, for some reason).

That should work.  Replication generally works fine, but they have made 
fixes and improvements over time, so the newer (stable) version you run, 
the better.  The only times I have really had any issues in production was 
with 4.1, and that was mostly only with manual deletion of objects with 
ldbedit not getting replicated.  I'm not really sure what's going on with 
4.4 or newer on CentOS 7.3.  As far as I know, there should be no 
replication issues with older versions.
