Planning on upgrading all the client systems to 10.11.5 however I need to know if I can since the back-end is still running 10.10.5. Last time it updated i had to rebuild the server to get it to work correctly.
Sorry my OP cut the first sentence. We need to make sure that XSAN 4 will work with clients running XSAN 4.1 (concerns with security certificate etc..)
