Uninstall your vm3, install the latest vm2.6,... copy your virtuemart_tables of the vm2.0.20b installation, then use "update tables" in the tools, then install vm3 over it, done.

The normal way is described here http://docs.virtuemart.net/tutorials/installation-migration-upgrade/198-upgrade-virtuemart-2-to-virtuemart-3.html
