Re: Volume group
vgexport -s -m /tmp/vgXXmap /dev/vgXX
mkdir /dev/vgYY
mknod /dev/vgYY/group c64 0xYY0000
vgimport -s -m /tmp/vgXXmap /dev/vgyy
Note that the map name remains the same while the VG name changes.

Re: Volume group
For a non root filesystem I followed this way (from HP k-mine):
1. umount /filesys (for each mounted filesys)
2. vgchange -a n /dev/vgname
3. vgexport -m mapfile /dev/vgname
4. vi mapfile (to set up new logical volume names)
5. mkdir /dev/vgnewname
6. mknod /dev/vgnewname/group c 64 0x
7. vgimport -m mapfile /dev/vgnewname /dev/dsk/cxtyd0
Where x and y are the device files for the physical volumes in the VG.
Hope it'll help.
