ConfigMgr SP2 Secondary Sites

Upgrading a ConfigMgr Secondary site with SP2 can be a little tricky. There are 3 ways that I tend to use to update them..

Secondary Site Upgrade Wizard

Preinst.exe /upgrade

Create a package for Software Distribution
This package needs to contain the downloaded prereqs and can be a little tricky to create. I put all the files in 1 directory and create a CMD file to install

install.cmd
SMSSETUP\BIN\I386\setup.exe /upgrade %cd%\prereqs-sp2
