Between all the custom symlinked directories, applications, etc, plus the sheer volume of data that would need to be backed up, an in-place upgrade would be infinitely more desirable. If it comes to the point of having to back up and do a fresh install I suspect I would be using the 6.x series anyway. I was really hoping that some way of upgrading in-place were available for vinum. Sven DSW> Sven, your best bet will be to build a set of disks off-line and then swap them in. That's the only way you can be sure to do it right. Ask yourself if the cost of finding and building a mule is worth more than the pain of screwing up.=20 It _is_ well worth doing, there were many things that were still unglued in 5.2.1. -- Don Wilde Org 01737 505-844-1126 Earth Halted: Please reboot to continue
