After upgrading an NSX deployment in VCF Operartions, you observe that NSX components continue to report the previous version in the UI.
example: 4.2 to 9.0
VCF Operations
NSX
This issue occurs because the NSX upgrade process did not reach full completion within the NSX Manager. VCF Operations reports the version based on the active state of the NSX Manager; You will also see the old version from help->about in the NSX UI. If the upgrade workflow is paused or requires manual intervention (showing "Continue with Upgrade"), the reported version will not update to the target baseline.
To resolve this issue, complete the upgrade process manually within the NSX Manager:
Log in to the VCF Operations UI and confirm the NSX component now displays the correct version.
Reference on performing an inventory sync if needed:
NSX upgrade cancels automatically in VCF Operations 9.0.2
