Best Practices for deploying Adobe CC Packages

We have a Team's license and use the Adobe CC packaging tool. Our packages are being deployed through SCCM 2012 but they fail because of insufficient cache size. Is there a best practices document for deploying Adobe CC packages in SCCM 2012. What is the recommended cache size?

It seems it must need to be quite large as when deploying CC Complete 2015 we have to also uninstall CC Complete 2014 and this equates to 60GB +. (If we don't do the uninstall of 2014 in the 2015 SCCM package then 2014 remains on the end user's machine by default.)

In our environment we have to download the package onto the user's machine installing from the DP is not an option.
