I don't know that this will be a major problem if my experience
years ago going from Caldera OpenLinux something-or-other to SuSE
Pro was any example. The old Caldera system had a multi-disk
LVM RAID which I had moved to a newer system, fully expecting to
lose the data after installing a new Linux OS on the system.
I did a fresh install on the primary HD without touching the
external RAID drives, and, much to my surprise, the new Linux
found the RAID drives, asking if I wanted to mount them.
