Change the update server address
You can change the update server address on an update agent without reinstalling it.
On the update agent computer, go to
C:\ProgramData\Milestone\XProtect Update Manager\Agentand open theserversettings.jsonfile.If you can't see the ProgramData folder, enable the setting to view Hidden items in File Explorer.
In Hostname, change the value to the new IP address of the update server. For example:
Hostname": "192.168.2.65",.
You can now log in to the update server using the changed address.
