I have mounted the content DB of my SP2010 site to the newly created SP2013 farm. The upgrade completed but with errors. When I try to view the logs, I kept on getting the " Failed to call GetTypes(), Exception: Method 'getChangedItemIdentity' in type 'Microsoft.SharePoint.BusinessData.Runtime.IdentityNotificationParser' from assembly 'Microsoft.SharePoint, Version=15.0.0.0, Culture=neutral, PublicKeyToken=71e9bce111e9429c' does not have implementation.
I tried upgrading the site through powershell and Site Collection Upgrade in Site Settings but to no avail. The error kept on appearing in the logs. I have read other blogs and forums and I think it does have something to do with BCS? I am still not sure about this. I need help asap! T_T
I am using WINDOWS SERVER 2008 R2 SP1, SQL SERVER MANAGEMENT STUDIO 2012, SHAREPOINT SERVER 2013.
