Sitecore 7.1升級 - System.Xml.XmlException在安裝更新包時

Question

我試圖將Sitecore從7.0（rev。130424）升級到Sitecore 7.1（rev。130926），並且每當我嘗試在更新安裝中安裝更新包時嚮導。它每次都在某個時刻陷入停滯，下面是我看到的日誌異常。

我在分析軟件包時看不到任何錯誤，但在嘗試安裝更新程序之後，此異常被記錄下來。

在嘗試更新時是否有其他人面臨此問題？任何線索？

Answer 1

我以前沒有遇到過這個問題，但它看起來像項目上的__renderings字段已損壞。

您應該能夠確定哪個項目作爲更新安裝嚮導將跟蹤它所更改的所有項目，並將它們打印在屏幕上 - 這將是最後更改的項目。

一旦您確定了該項目，找到它（通過guid）並查看該項目的標準字段上的佈局部分。打開頂部功能區中的原始值，並在字段中使用xml查找問題。

一旦糾正，再次嘗試重新運行更新嚮導，看看是否可以解決問題。
