time finder clone on AIX

Hello, I am trying to clone an AIX volume group for the first time. The volume group is made out of 3 devices (DEV001, DEV002, DEV003). I'm trying to clone them to the target devices DEV004, DEV005, DEV006 on the secondary host. I have created the device group below -

root@wfscr04:/prod/oe/b/db#symclone -g oebdg query


Device Group (DG) Name: oebdg
DG's Type : REGULAR
DG's Symmetrix ID : 000187461303

Total --------
Track(s) 8650795
MB(s) 270337

I have run the following commands on the primary host -
symclone create DEV001 sym ld DEV004
symclone create DEV002 sym ld DEV005
symclone create DEV003 sym ld DEV006

symclone activate DEV001 sym ld DEV004
symclone activate DEV002 sym ld DEV005
symclone activate DEV003 sym ld DEV006

I then went to the secondary host and ran -
cfgmgr
importvg -y b_db10vg hdiskpower10

The import fails with the following message -

root@wfscr12:/#importvg -y b_db10vg hdiskpower10
0516-002 lqueryvg: The volume group version is incompatible with this level
of the operating system and cannot be activated.

I'm not sure why the error. Should I have run an exportvg on the source server before trying to importvg on the target server? Both servers are running AIX 5.2 ml 3.
