We successfully ran on Centos 7.3 with 4.4.4 and 4.5, the 4.5 having been installed later. The first step in installing the replica was that it automatically upgraded itself to the newest release, so it happened without giving us any choice. We later upgraded everything to 4.5.
4.5 have generally been OK, though the gssproxy that came with it seems to have a serious memory leak. We have to watch it and restart it when it gets too big.

Anyone out there with experience of whether or not adding a replica of more recent version (4.4.4 and 389 dir 1.3.7.5-1 up from 4.4.3 with 389 dir 1.3.5.15-2) would impact the existing servers in terms of schema or similar? I'm still trying to find a safe way to upgrade safely without going past a point of no return...
