Sitecore 7.1升级 - System.Xml.XmlException在安装更新包时

Question

我试图将Sitecore从7.0（rev。130424）升级到Sitecore 7.1（rev。130926），并且每当我尝试在更新安装中安装更新包时向导。它每次都在某个时刻陷入停滞，下面是我看到的日志异常。

我在分析软件包时看不到任何错误，但在尝试安装更新程序之后，此异常被记录下来。

在尝试更新时是否有其他人面临此问题？任何线索？

Answer 1

我以前没有遇到过这个问题，但它看起来像项目上的__renderings字段已损坏。

您应该能够确定哪个项目作为更新安装向导将跟踪它所更改的所有项目，并将它们打印在屏幕上 - 这将是最后更改的项目。

一旦您确定了该项目，找到它（通过guid）并查看该项目的标准字段上的布局部分。打开顶部功能区中的原始值，并在字段中使用xml查找问题。

一旦纠正，再次尝试重新运行更新向导，看看是否可以解决问题。
