The Windows Server Update Services content can be moved after the role has been installed and configured using the WSUSUTIL.EXE utility. This can be found on your WSUS server at the following location: “%PROGRAMFILES%\Update Services\Tools\”
You will need to create the directory on the destination location first before running this command, for example D:\WSUS
The command to run is:
wsusutil.exe movecontent "CONTENT PATH" "LOG FILE"
for example:
wsusutil.exe movecontent D:\WSUS\ D:\wsusmove.log
