All our current freeipa servers are running Centos OS 7. We are thinking of moving to Red Hat in order to get better support. Is it possible and safe to have some Centos ipa masters and some Red Hat ipa masters in the same domain/cluster? If yes, that could make this move very easy and smooth - just swap in RedHat master and swap out Centos masters. 

I'd like to know if any one made such a move in the past and how it went. 

Thanks! 

Kathy.
