Are there any foreseeable issues with having instances / nodes / clusters on different releases of glassfish all tied into a single domain?
For instance, say I have a domain that has 3 different clusters in it, and 1 cluster needs to upgrade for some reason. Is it going to cause any issues to have the Domain manager and nodes on dissimilar versions of glassfish?
[ DM GFv2UR1] [Node01 GFv2UR1] [Node02 GFv2UR2] [Node03 GFv3] etc.
Also, when you upgrade, whats the lowest level scope you can upgrade at? Can I upgrade at an instance level / cluster level or does it have to be at a node level?
TIA,
Andrew
