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)
