Make sure your PM Cloud instance is upgraded to 24.7

Then if you are using the Package Manager, it is as easy as setting the client and adapter version on the Computer group in PM Cloud.

If not using the Package Manager, get the Adapter and Client downloaded from your PM Cloud portal, then do an install “on top of” using the same command line strings as initial installs.
 

I do recommend test updates on a smaller groups of computers first, just to validate you do not have issues with latest and greatest version.
