Pulp

Chris got this error after upgrading from 2.5.0 to 2.6.0 alpha:

The cause is the ReservedResource model change [0]. The solution is to create a new migration that deletes all documents from the reserved_resource collection. It's safe to do because the workers will recreate them once they start with the right attributes for the 2.6 code.
