Migrating VM from J!1.5 TO J!2.5 - having issues

[GooRu]

Hi folks, need some help here. I have a new J!2.5 install and an old J1.5! site with VM 2.0 (now on both). I exported the old DB VM_tables and imported them into the new install with the latest VM.
I also copied over the images to the correct spot.

I use the migration function in new install, and it does recognize the images and deals with them, but does not covert the old tables. I've been banging on this for some time, anyone got some good advice?
