Change source control from visual studio to RTC: questions for updating solution and project files

The topic "Migrating from another source control provide to jazz" in CLM Information Center is confusing about exactly what to do. It does not show a specific example for Visual Studio.

I am moving source control provider from TFS to RTC and would like to know the following

1. The section in the solution files: should I just look at GlobalSection(TeamFoundationVersionControl)? And what to remove in that section?

For example, I have the following section. Should I remove all lines for the section? If so, will I lose the project dependency defined here?
 
    GlobalSection(TeamFoundationVersionControl) = preSolution
        SccNumberOfProjects = 14
        SccEnterpriseProvider = {4CA58AB2-18FA-4F8D-95D4-32DDF27D184C}
        SccTeamFoundationServer = <TFS URL>
        SccLocalPath0 = .
        SccProjectUniqueName1 = <p1.csproj>
        SccProjectName1 = <some name>
        SccLocalPath1 = <path>
        SccProjectUniqueName2 = <p2.csproj>
        SccProjectName2 =<some name>
        SccLocalPath2 = <path>
        SccProjectUniqueName3 = <some name>
        ...
      EndGlobalSection

2. In the *.csproj project files, what should I be looking for? Should I look for <SccProvider> section?

Should I remove the following lines from all csproj files?

        SccProjectName = "SAK"
        SccAuxPath = "SAK"
        SccLocalPath = "SAK"
        SccProvider = "SAK"
