  • Question

  • Hi All,

  • In general scenarios, yes it's possible to upgrade the windows server from 2008 R2 to 2012 R2 in-place for SharePoint 2013 Farm.

    Microsoft Knowledge Base article 2818510 describes the standard procedure to execute such an upgrade.

    But it's heavily recommended to do not do that on the production servers. Recommended path for SharePoint Server would be to add servers with the desired/supported version of Windows Server to the existing farm. Minimal configuration should be required (IIS Bindings and SSL certs, any 3rd party apps you need to install locally). Other artifacts, such as WSPs are stored in the Config database and deployed as part of a Web App/farm deployment. DNS records may need to be adjusted. Search topology will need to be adjusted. As you add new SharePoint servers to the farm, eject the old ones they replace.

    Web.config changes should never be made by hand, instead using the SPWebCofnigModification class.

    This is the supported method to upgrading SharePoint servers to a newer version of Windows Server -- but you shouldn't remain in a mixed-OS state for SharePoint servers for very long.

    For SQL - SQL can be upgraded via standing up a new SQL Server, restoring the databases and re-connecting the SP Farm.
