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.
