If I suppose you can install and boot you old disk in you new system
together with the new disk, you can do the following (I suppose the old
disk is /dev/hda with a /dev/hda1 partition, and new one /dev/sda with
a /dev/sda1 partition, I suppose your volume group is vg0):
make backups ;-)
- pvcreate /dev/sda1
- vgextend vg0 /dev/sda1
- move all the lv data with pvmove /dev/hda1.
- vgreduce vg0 /dev/hda2
- you will have to configure lilo/grub to install and point on your new
disk.
I've done such a way but it was not with lvm2. Maybe there are some
pvmove issues with lvm2.
