At some point I (without thinking, I assumed premigration.zip had everything I needed) deleted the pre-migration directory from the appliance, and it's giving me problems updating to version 6 - specifically when I run the premigration script, I see:

Warning: Could not find file /usr/local/vkernel/toos/pre-migration/rest-api-schemas.jar

Is there a way to get just the files populating pre-migration so I can get them back on the appliance, or will I have to load a new virtual appliance?
