I'm trying to upgrade one of our sites from 5.4.4010 to 7.3.5630. The upgrade process using the Project Manager completes fine without any errors, but all the upgrade is doing is updating the Telerik DLLs to version 7.3.5630; all the config files and database tables remain on 5.4.4010, so when I try going to the site I get the following error:
Could not load file or assembly 'Telerik.Sitefinity, Version=5.4.4010.0, Culture=neutral, PublicKeyToken=b28c218413bdf563' or one of its dependencies. The located assembly's manifest definition does not match the assembly reference. (Exception from HRESULT: 0x80131040)
I thought I'd try upgrading to 5.4.4040, but the same thing happens. The connection details in the DataConfig.config are definitely correct.
Is there any specific reason why the config files and DB would not be updating?
