hi,
after my first post I made a move, I should say a smaller 
rather, I did migrate a small HA cluster from SL7.1 to 
Centos7.2.
Instructions to do that I'm sure everybody can easily look 
up, just one tiny manual intervention was needed above what 
is already covered by a doc on Centos website.
But most importantly nothing broke, all the usual servers, 
web, mail, other net related services including HA carried 
on seamlessly.
Like I said earlier, and everybody knows, a lot, a lot is 
already shared, differences boil down to maybe a philosophy 
behind each organization responsible for each snip-off, some 
organizational and administrative processes, protocols.
Slight advantage seems that Centos offers, but expected as 
they are closer to the source in the lifecycle supply chain, 
is higher revision of some rpm packages, I see I get 
slightly newer kernel for example, etc.

If I was to voice my opinion out - and scientific devel & 
other responsible culprits are listening - then I say: go 
for it, get together, merge userbase, share devel jobs, 
duties, etc. Merge/share or even better, tell Redhat we want 
to use their, shared by all, bug reporting system.

I've decided, I'll be moving over to Centos, gradually but 
surely.
Note, one thing to remember if you did SL -> Centos, 
afterwards, is yum repos, make sure what you have enabled there.

cheers
