We've one the 3.0.1 to 3.5 upgrade and have discovered that the patch level on the 3.0.1 servers makes a difference. If the servers are early versions of 3.0.1 and haven't been patched VMotion may not work between the 3.0.1 to 3.5 servers. You can shut down the guest and move them easily to the 3.5 servers - but live migration fails.
