Inplace upgrade - 2008 r2 to 2012 r2 standard fails

I'm Suraj 6 Reputation points

Hi All,

I have a server running on windows 2008 r2 sp2 standard and want to upgrade it to 2012 r2 standard version. But whenever I mount the ISO and trigger the upgrade I get a error like attached below and the installation fails.

  1. Server restart and trying again the installation is not working
  2. There are no anti-virus programs running on the server that is blocking the upgrade
  3. The server has enough resources w.r.t RAM, CPUs, C drive space.

P.S - Building a new server and migrating the applications to the new server is not an option available for me here. so kindly take out this option.211895-microsoftteams-image.png

Any help would be appreciated. TIA.

    An in-place upgrade is risky and can be problematic. Better option is to clean install and migrate roles over. You can also review the log files.

    Thank you for your question and reaching out. I can understand you are having issues related to Upgrade to 2012 R2.

    It looks that issue with User profile , please try to rename the profile or Try to run setup from different user profile.

    Please , Disable any Antivirus program or Windows firewall you may have for temporary purpose.

    Please also investigate using upgrade log file to know exact error.
