I would like to understand how to move a LVM VG from one machine to

about moving VGs.

I feel
like I can't follow the instructions in the HOWTO because it wants me to
unmount the file systems, export the LVs and so on, on the old machine
before moving the disk, and I don't see how I can do that on a system
that is expecting to use those file systems to operate.
you must have missed:
"vgexport/vgimport is not necessary to move drives from one system to
another. It is an administrative policy tool to prevent access to
volumes in the time it takes to move them."
Just move the disk and the lvm stuff will show up like normal. The only
potential gotcha is if you used the same volume group names on both
systems, then that would need to be resolved (by renaming one of them)
