Replacing a old SMG server

I am going to replace our SMG server version 12/17/20 v163, because I have not been able to get it to upgrade, it crashes, plus I want to get it on a new hardware.   But the old Ubuntu update does not work with the new SLES SMG servers.   I have not seen any docs on the moving the SLES servers to a newer one.   Can I just copy the /vastorage volume to the new server, like you can with updating Filr??
