It's a best/general practice to set up metadbs on both disks. Detaching
the mirrors should work. Make sure that /etc/init.d/lvm.sync has the
metasync -r line commented out so that the mirror resync wouldnt start
across reboots. You can chose to use Liveupgrade 2.0 while you have the
system up and running. Live upgrade 2.0 Guide tells how to upgrade when
you have boot disks mirrored with SVM or encapsulated with VXVM.
