I just need to get my infrastructure done while waiting for 6.5. As usual, not really sure when 6.5 will be general release. I still need to work in the meantime, so I need to migrate the current setup. If/when I upgrade to 6.5 the hardware will be all ready. I was running AC 6.0.9 on the SBS Server 2008, and recent updates of SBS made it more of a resource hog. I am trying to get a hyper V replica going, installing separate AC server and its replica on different virtual and physical servers.
