ConfigMgr 2012 SP1 Beta (released) here is Full Installer. To test ConfigMgr SP1 Beta, we don’t need to install SCCM/ConfigMgr RTM and upgrade it.
I’ve tested “direct install” of ConfigMgr 2012 SP1 beta and it’s successful.
If you don’t have ConfigMgr 2012 RTM environment, you can just download and install ConfigMgr SP1 beta directly. No need to install RTM (first) and upgrade RTM with SP1 Beta.
Hope, you’re aware of the fact that “BETA” release is not for production environments and it’s not supported or you won’t be able do a direct upgrade from “BETA” to “SP1 RTM”.
Out of curiosity, checked the size of RTM and SP2 Beta Folders.
ConfigMgr_SCEP_2012_SP1_Beta_ENU_7782 = 541MB ConfigMgr_SCEP_2012_RTM_INTL_7711 = 1.55GB
Why is this different in size?
