NSX Manager to Policy objects promotion fails with error Config Translation Failed

Products

• VMware NSX

Issue/Introduction

The operation to promote manager objects to policy in the NSX UI fails with the following error:

Environment

VMware NSX 4.2.x

Cause

This error occurs as a result of a stale ServiceConfig object that is still present in NSX.

Resolution

1. Delete the stale ServiceConfig using the API call:
  DELETE https://<nsxmanager>/api/v1/service-configs/UUID

  Verify there is no production DFW policy currently using this ServiceConfig. 

2. Retry the promotion — after cleanup, restart the MP→Policy migration from the UI.
