Agreed. I have run clusters with both RHEL5 and RHEL6 nodes.

Will it work without issues? Rational: We have a 40 servers cluster which was originally installed only with Ubuntu servers. Now we want to move to CentOS 7 but the effort of reinstalling the entire cluster + migration to CentOS 7 is not simple. So we thought about adding new CentOS 7 nodes to the existing cluster and gradually remove the Ubuntu ones. Would love to read your thoughts.
