  • Yes, SP1 (and I think even CU2 for SP1) is required.

  • Hah! Here is a link from technet that addresses SP1 and CU!

    http://technet.microsoft.com/en-us/library/jj822981.aspx#BKMK_UpgradeR2Checklist

    Ensure all sites in the hierarchy run System Center 2012 Configuration Manager with SP1.

    You cannot upgrade a site to System Center 2012 R2 Configuration Manager until all sites in the hierarchy run System Center 2012 Configuration Manager with SP1. The version of cumulative updates for Configuration Manager that are installed at sites is not evaluated and you can upgrade a System Center 2012 Configuration Manager SP1 site regardless of the cumulative update version that is installed, or even when no cumulative update is installed.

    ...sorry MS for my early comment about the missing information :)

  • I haven't come across official documentation, but this site says: "In order to be able to upgrade to ConfigMgr 2012 R2, you need to have SP1 installed in your hierarchy."

  • I can't find anything to support the CU requirement... Only SP1 "Upgrade to R2 is possible only from ConfigMgr SP1 with Windows ADK 8.1".

    Would be nice to get an official answer from MS. 1-800-what? :)

  • Until it goes RTM and maybe even GA, there won't necessarily be an official answer. It's not like you can upgrade to it today anyway so it's not like it affects much. Installing a CU is a straight-forward process that takes just a small amount of time. If you're doing your planning, just plan on doing it.

  • Has anyone tried upgrading clients from RTM to R2. The link

    http://technet.microsoft.com/en-us/library/jj822981.aspx#BKMK_UpgradeR2Checklist

    Upgrade clients.

    After you upgrade a primary site, plan to upgrade clients that are assigned to that site. Although a Configuration Manager primary site or secondary site can support communication from clients that have a lower service pack version (including clients that run Configuration Manager SP1 talking to a site that runs System Center 2012 R2 Configuration Manager), this communication should be a temporary configuration. Clients that run a previous service pack version of Configuration Manager cannot use the new functionality that is available with the new version of Configuration Manager.

    When you upgrade a client, the current client software is uninstalled and the new client software version is installed. To upgrade clients, you can use any method that Configuration Manager supports.

  • You're not actually upgrading the client. The existing client is uninstalled and R2 is installed. You can do this using "Automatic Client Upgrade" (perhaps named badly), manual install etc.

    What the extract above is telling you is that you do not necessarily have to upgrade SP1 clients straight away as they will still communicate (although you are strongly advised to do so).

    And yes, the process works pretty well.

    If you have RTM clients you could install the R2 client using Group Policy.

  • Does the RTM clients continue to communicate and function to R2 until they are upgraded.

  • Yes the clients should communicate.
