I wann to Upgrade from TFS 2013 to Azure DevOps Server 2019. I am unable to uninstall the old one, the only thing i can do is to unconfigure the Application Server. But then the installer tells me that an installation is not possible without uninstalling the TFS 2013.

You can uninstall TFS 2013 from the Control Panel, go to Control Panel->Programs and Features->Uninstall a program.

Before go to control panel to uninstall, you need to remove the configured Extensions(eg. SharePoint Extensions), go to Team Foundation Administration Console->Extensions for SharePoint Products.

  • that dosnt work for me because some systemrights (my user was administrator). I used some random uninstaller from the internet – Steini Jul 09 '20 at 13:52
  • So you successfully uninstalled the TFS 2013 by using the random uninstaller. Right? If yes, Could you share the uninstaller and post it as answer to your question? – Levi Lu-MSFT Jul 10 '20 at 09:27
