你以为这样升级就完了么？

没有，长征的路，还很长。。。

可能尽管配置了WINRM IIS Extension

IIS里也作了相关的KERBOS之类的认证和BASIC WINDOWS认证（POWERSHELL目录）

可能打开EXCHANGE2013的POWERSHELL管理窗口时，还是会有莫名的错误。

Connecting to remote server failed with the following error message: The WinRM client received an HTTP server error status (500), but the remote service did not include any other information about the cause of the failure. For more information, see the about_Remote_Troubleshooting Help topic. It was running the command 'Discover-ExchangeServer -UseWIA $true -SuppressError $true'.

又有可能，啥都好了，但总有一个关于SHAREPOINT的进程占用超多内存。。。。XXX。
