NFA to Portal Circular Reference Synchronization failure

Issue/Introduction
Duplicate groups are seen from Data Sources integrated with Performance Management.
This is often observed after a Data Source is deleted and added again to Performance Management.
The duplicates of the groups are coming from Performance Management. They are contained in the Data Source Orphan Groups list. To see that that list is found on the Manage Groups page via Administration->Group Settings->Groups.
Once on the Manage Groups page select:
- All Groups -> Inventory -> Data Sources -> Data Source Orphan Groups -> User Defined Groups -> <group name>
This can be seen for the following Data Sources:
- Network Flow Analysis (NFA)
- Application Delivery Analysis (ADA)
- Unified Communications Monitor (UCM)
Environment
All supported Performance Management releases
Cause
At some point the NFA Data Source was deleted from Performance Management then added back again.
When a Data Source is deleted, Performance Management does not remove the Groups. Instead it moves them into a Data Source Orphan Groups list. Once NFA is added again and re-integrated with Performance Management the group was synchronized to Performance Management a second time.
The end result is two instances of the Group. One is a working version of the group and one which is orphaned.
Resolution
To resolve this we will remove the Groups that are orphaned to ensure there is only one instance of the Group showing in Performance Management.
In the Manage Groups page go to the Orphan Groups list and delete all present.
- All Groups -> Inventory -> Data Sources -> Data Source Orphan Groups
NOTE: The 'Data Source Orphan Groups' Group will only be visible in the Group section of the UI if the system does in fact have orphaned groups due to an originating data source having been removed. If it is not present, no cleanup via Group deletion is required.
In the Manage Groups page to the Data Sources User Defined Groups and delete all present.
- All Groups -> Inventory -> Data Sources -> <Data Source> -> User Defined Groups

Resolution
Remove all entries in All Interfaces (Groups->Inventory->Data Sources)
Delete the "Data Source Orphan Groups" group (Groups->Inventory->Data Sources)
Perform NFA full resync
