Which way is the best I can't tell, but mirroring is probably one of the
easiest.

ok so :
i add the new disks to the volume group i need to change the disks,
then i mirror the volumes to the new disks, when i have a mirror for
every logical volume i can vgreduce the old disks.? nothing else to
do?

Once your mirrors are all sync'd, you'll also need to 'lvreduce -m' for each LV
to get the old disks out of the mirror before you can vgreduce.

This should work, provided the PE size of the VG is big enough to
allow you to use all the space on the new LUNs.
Only an issue if there is a large difference in LUN size between the
old array and the new array.
