Is your VMS license hardware procected ? If yes you will need new PAKs If not you should trailor down instalation on 3100 to fit into 2000's disk, then make standalone backup. There would be probably another problem - your 2000 disk arangemant may be different, so logicals pointing to those disks (especialy system disk) will fail. I think the best way is restoring that backup on 3100 with 2000's disk hooked to it and then editing all config files. Next put that disk back into 2000 and ATOGEN. But first check up PAKs Maciek Peter Joules wrote:
