Update to the feature release 11.24.x

No problem to delete the software cache, and you can do it through the Commcell Console/Add remove software, and you get the ‘Delete software cache’ button.

But I would recommend you to setup a remote software cache to some other location, where you can get and keep your previous sources in case you need them.

When the remote software cache is synchronized and populated, you could disable that remote cache, then delete cache content from your CS, then you can initiate the download software to your new version. When complete, you’d have new updated sources on your CS, and old sources somewhere else.

Now, regarding the upgrade itself, though it should work this way through the console, I would recommend you to initiate it manually, opening an explorer to your valid and updated software cache location, and run as administrator the setup.exe from there, and chose the upgrade as you want.

From there, you’d master all the steps of the upgrade, whereas from the console, when it’s initiated, you don’t have much feedback/output on the process, except a installation progress bar on the Commserve itself.  

edit : tip for you, type the Windows key on your keyboard, and input CAPTURE and enter.
