Some time ago, I wrote about the release of the cumulative update for March and April for SharePoint 2013.
Note that a new update was released in June! Always available via the same address: http://technet.microsoft.com/en-US/sharepoint/jj891062
Again, this cumulative fixes an error that may occur during a SharePoint migration from 2010 to 2013.
Among the issues corrected:
« After you upgrade from SharePoint Server 2010 to SharePoint Server 2013, certain list items cannot be correctly rendered. Additionally, you receive the following error message: An unexpected error has occurred.”
Think about it !
