I finally upgrade my System Center Configuration Manager form RC version to RTM version with SP1 included.
As I had “small” collation problem I couldn’t just simply reinstall it. For that reason I was uninstall my SCCM completely. Plan was to keep server name in Active Directory and to keep same site name.
In that reinstallation I was separate my SQL server from my SCCM server. Now I have SQL 2012 SP1 for all (future)System Center products, and SCCM is connected to it.
After one working day my job was done and I have fully functional SCCM. Now I have to wait for clients to contact SCCM. Most of clients were contact SCCM in next two days, but some clients don’t.
