Folks, Please, I need help to deicide how to migrate my SCCM 2007 clients to SCCM 2012 clients. I saw some posts on the Internet, but nothing to clear to know the best and FAST way to do that.
Current Scenario (SCCM 2007): I have 1 CENTRAL SITE and 3 PRIMARY SITES all in same location, I have 3 branch offices with SECONDARY SITES + DP, each branch office have 300 SCCM CLients installed on desktops. New Scenario (SCCM 2012 side by side 2007): I have one CAS + PRIMARY, each BRANCH OFFICE I will have just CM 2012 DP. What is the BEST and FAST way to migrate my SCCM 2007 CLients from branch offices? Currently I will have SCCM 2007 DP on each branch location and this will be migrated only affter ALL SCCM CLient by upgrated to SCCM 2012 clients. Any suggestions here?
