I've been trying to get XenServer 5.5 upgraded to 6.0 on my Rackable Systems boxes with Intel S500PSL boards. However when booting the install it freezes when i select an option at the splash screen. I can't get to a shell or to the installer, has anyone experienced this or know how to fix it?
Apparently you cant upgrade from XS 5.5 to 6.0 directly. You have to pass through XS 5.6 first. Check Tobias's answer: http://forums.citrix.com/thread.jspa?threadID=294812
