Ran the ZDC on our external database in preparation for the upgrade from 10.3.1 to 11. These are the errors we're getting:

ERROR Missing object in table 'NC_NetworkPrinter_Consumable'
Object type: [Index] , Object name: [idx_NDConsumable_OID]

ERROR Mismatch in table 'zPolicyDef' structure.
Object type: [Column] , Object name: [ComponentName]
Expected: [Name: ComponentName, Size: 64, Type: VARCHAR, Nullable: true]
Found: [Name: ComponentName, Size: 64, Type: VARCHAR, Nullable: false]

Should these be corrected manually, or with a db rebuild?
