This probably deserving of a thread all to itself, but from what I
understand, you have two disks, each with LVM, with distinct VGs. You
might do better to use the LVM names for these things - you cannot, for
example, 'mount' anything LVM related except for an LV, but normally an
'LVM partition' means a partition used as an LVM PV - to avoid
confusion here.

Anyway, what I'd do in what I think is your position is put one of the
drives (presumably the old one) in a machine and rename the VG (with
vgrename) before putting it back. What is the output of vgdisplay and
of pvdisplay ?
