If you backed up your .virtualbox directory before you upgraded and made no changes to any virtualboxes while using 2.0.2, no it should be OK.

If you didn't backup your files you'll end up doing a lot of editing of your xml files for 1.6 to recognize them again.

Yes, you need to edit the machine.xml files but it is quite straight forward. See the 1.6.6 announcement in the "Using VirtualBox" forum for more details on how to do this.
