Edit lvm.conf to hide the old disk. [with a filters line]

Then you can add the disk to the machine and lvm will ignore it.

Create a temporary 'lvm' directory somewhere else and copy
lvm.conf into it and reverse the filter so it *only* looks
at your old disk.

Set environment variable LVM_SYSTEM_DIR to your temp dir.
and run 'vgrename' to change the name of the VG.

Then get rid of the environ var & the temp dir and reset
the filter in lvm.conf so it sees everything again.
