In NSX-v, the 'Upgrade Coordinator' fails with 'Internal server error'

Products

• VMware NSX for vSphere

Issue/Introduction

• The NSX-v Manager UI will failed to load 'Upgrade' pane/page with an error 'Internal server error has occurred'. 
• Users cannot perform a 'one click' upgrade or plan and start an upgrade from 'Upgrade' navigation page
• Issue is observed in upgrades to 6.4.5 and later
• Stale agency IDs exists from old NSX-v versions

 

Environment

VMware NSX for vSphere 6.4.x
VMware NSX Data Center for vSphere 6.4 Extended Support

Cause

The issue is caused by stale deployment units that exist in the NSX-v.
The corresponding agency will still be present in the EAM MOB in VC.
As a result, the Upgrade Co-ordinator would be unable to load available 'Clusters' along with other inventory collection, where some of the clusters were non-existent any more, but their agencies still exist.
