我在TFS2015.4上遇到特定團隊項目集合的問題。這個集合在我以前還想升級TFS時也會引發問題。我能夠在TFS2013.3中分離它，然後進行升級。現在我想升級到TFS2017，我不知道如何解決這個集合的問題。TFS 2015.4無法啓動或分離集合
TF400868: Job definition not found for JobId d891ac97-ddf1-42df-8242-3cd4bd607790
這是當前的狀態：
- 不會脫離
- 不會啓動
- 狀態 - > ApplyPatch - >將不執行
- 保持脫機狀態
- 裏面的一個項目，並保持'刪除'狀態
如果我嘗試啓動，我得到這個錯誤：
TF400783: The host 'MyDAS' cannot be started. The host is in the process of being serviced. The servicing may have failed and needs to be restarted and completed before the host can be started.
我做了一個預生產升級到TFS2017並有與使我未能完成升級這個集合的狀態驗證錯誤。
詳細的日誌ApplyPatch重辦只有一個故障點：
