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\Agent and open the serversettings.json file.
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.
