Take a peek at this:
IBM Knowledge Center

Sorry, I don't have much time to go into depth on this one right now, but yes you can export the vg and import the vg on a new system.
example:
NodeA

unmount all FS
varyoffvg <vgname>
exportvg <vgname>
rmdev -dl hdiskX <where the vg resided>

NodeB

Assuming everything is zoned for the lun.
cfgmgr
lspv to find your new hdisk
importvg -y <vgname> hdiskX
mount the filesystems
change characteristics as needed for the VG and FS

Should be noted that importvg creates file mount points and entries in the /etc/filesystems

vgimport

VGIMPORT(8)						      System Manager's Manual						       VGIMPORT(8)

NAME

       vgimport - make exported volume groups known to the system

SYNOPSIS

       vgimport [-a|--all] [-d|--debug] [-h|-?|--help] [-v|--verbose] VolumeGroupName [VolumeGroupName...]

DESCRIPTION

       vgimport  allows  you to make a Volume Group that was previously exported using vgexport(8) known to the system again, perhaps after moving
       its Physical Volumes from a different machine.

OPTIONS

       See lvm(8) for common options.

       -a, --all
	      Import all exported Volume Groups.

       --force
	      Import exported Volume Groups even if there are missing Physical Volumes.  This option should only be used if  the  missing  devices
	      are known to have failed and they cannot be restored.
