Is anyone aware of maximum OS compatibility of FileMaker Server 10? I have a customer looking to upgrade to a new server. I'm going to be suggesting to them upgrading their FM install, but they seem reluctant. Just getting any information I can. Technically they are v5.5 right now, but they told me they had bought FM Server 10 but had never upgraded to it. I've looked into that upgrade path. Not seeing anything on server compatibility though.
