What was the naming policy of the new and old luns (multipath.conf generic mpathxy or the administrator specified the names ?)

What method was used during migration (pvmove, lvmirror or ?)

Can you post :

Code:
cat /etc/lvm/lvm.conf
multipath -ll
vgdisplay -v <volume group in question>
dmsetup info


Was /dev/mapper/name used LVM/VG operations ?
