DJOS did you figure this out? there are some things I discovered after about an hour of head banging - for bunglehaze's instructions to work, you have to make sure your db tables all have the same prefix - the old tables will prolly be jos_vm_whateverwhatever and the new ones will have the randomly generated prefix that joomla 1.7 now does during installation, ie u37d_virtuemart_whateverwhatever - you can tell them apart real easily but for the migration thing to work in VM 2.0 you have to have them all the same prefix - whatever method you may use... The way I did it, was to tell joomla 1.7 to use the prefix jos, imported my old virtuemart tables with jos, and voila! Once I did THAT, worked great!! Then later, when I'm finished with the dev work, and I back it all up via Akeeba, put on live server, THEN I'll let joomla 1.7 assign a random prefix for all the tables... cool!
