I need to upgrade a ConfigMgr 2012 SP1 hierarchy with multiple secondary sites to ConfigMgr 2012 R2. All secondary sites have low bandwith connections to the primary site. We want to control the update process as much as possible.

Is there a way to prestage the installation files to be used for the R2 upgrade on the secondary

Hi,

As far as I know, there is not a way to prestage the installation files.

Thanks for your answer. I could not find it is possible in any documentation, I just needed to be sure.
