Migrate WSUS Content in Server 2012

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

Enable Deduplication in Server 2012

Windows Server 2012 brings a useful new feature for your file servers to give you more efficiency in your file servers. This feature can be installed from the Roles and Feature wizard on any Server 2012 or 2012 R2 operating system.

Microsoft provide a deduplication evaluation tool as part of Server 2012 so you can get an idea of the storage savings you could see on your system. This tool is called DDPEval.exe and can be found in the C:\Windows\System32 folder of your server. This can be run against an entire drive or a specific folder.
