我安装了 TFS 2013 v. 5（试用版），我想将其升级到 Azure DevOps Server 2019。
但我收到错误消息：“不支持从 Team Foundation Server 2013 直接升级。您必须先卸载 Team Foundation Server 2013，然后才能安装此版本的 Azure DevOps Server”。
我已使用 TFS 管理控制台删除了 TFS 应用程序层并重新启动了计算机。控制台显示：“此功能已安装但需要配置”。

这条线可能是原因：
Condition '(CurrentOperation = "Install") AND TfsDev12SharePointExtensionsCoreVersionExists' evaluates to true.
看起来它正在检测已安装但未配置的 Sharepoint 扩展，可能来自注册表项：

我错过了什么？
