After successfully upgrading Local and Global Managers in a federated environment, some locations may still show the old version number for the Local Managers in the Global Manager UI.
VMware NSX 4.x
This can be caused by if the Local Managers at a site are restored from backup, or it can be caused by issues with the order of the Local Manager nodes being upgraded.
To resolve this, SSH to a Local Manager of the affected site as root and run the following API:
curl -X POST -ik http://localhost:7999/api/v1/sites?action=refresh -H 'X-NSX-Username:admin;adminPassword'
Kindly refer to the KB article to enable the root access on NSX manager Enable ssh root access for NSX appliances
