Resource groups 9.05.700c

We are in the process of migrating to Epicor 9.05.700c from Vantage 5.1. Epicor converted our database and created a resource group called "converted rates for Vantage" that contain our job and quote costing rates. Their documention for cleaning up resource groups states that this group cannot be deleted. I makes it very confusing with how these are set up. Has anyone worked out a method to move the costs to the other resource groups and delete the "converted" group? I have our yahoo groups set to digest mode so it may take me a while to respond. If anyone would like to respond off list please feel free to do so. Thanks for any help
