I currently have SCCM 2012 SP1 installed, we have had some file corruption, most of the site is still working however I want to start over from scratch. So I have built a new server and SQL instance running both Windows server 2012 R2 and will use the latest’s SQL server that is supported. My question is, can I just install a new site, with a new site code and then reinstall clients pointing at the new site code? Do I have to add any schema extensions for the new site code?
