Sitecore 6.6到7.0升级

从sitecore 6.6.0版本升级。130529到7，在我尝试访问“内容编辑器”之前，一切都很好。我犯了这个奇怪的错误，不知道该怎么办

尝试了几次，但我看不出这种情况会消失。以前有人吃过吗

现在更新为完整堆栈。我不确定前两个异常是否与此有关，但这可能是问题的一部分。

错误来自Sitecore试图通过反射加载程序集，并在DLL上拒绝系统级访问。您应该检查应用程序池运行时使用的标识是否有权访问webroot，特别是/bin文件夹及其所有内容。

转到IIS并选择站点应用程序池。然后单击Advance设置并导航到Process Model部分。将标识更改为NetworkService

在网站文件夹上，右键单击并转到属性。选择安全选项卡并添加以下用户：

每个人-选中所有复选框以提供完全访问权限 此外，请确保网络服务出现在所有需要访问的用户名列表中：

你有更多的堆栈跟踪吗？@Marek我现在已经添加了完整的堆栈。你是否将升级后的安装与目标版本的干净安装进行了比较，以确保没有遗漏任何内容？@JayS这不是我做过的，但我想我也可以尝试一下。但随着sitecore安装的文件数量的增加，我想知道通过2k+是否可行files@dami_th不要手动检查。只需安装一个干净的版本，然后对两个网站文件夹运行一个diff工具，如BeyondCompare或KDIFF，然后查看deltasI。我已经创建了一个自定义用户并授予了完全权限，并使用它运行应用程序池。不幸的是，在web根目录中为用户提供了文件的完全权限。
