You'll probably have to do the other stuff the old fashioned way but you can
transfer your LVM data with pvmove. All you have to do is create a new LVM
physical volume, vgextend the volume group with the new partition, pvmove the
data over and then vgreduce the volume group.
e.g:
partition new disk to create LVM partition
pvcreate /dev/new_lvm_partition
vgextend whatevervg /dev/new_lvm_partition
pvmove /dev/old_lvm_partition
vgreduce whatevervg /dev/old_lvm_partition
If you had more logical volumes on LVM this would migrate all of them at the
same time. These days I have everything except the root filesystem in reiserfs
on LVM.
