I get an error when trying to upgrade my web app to the latest version of telerik.

When using the Telerik upgrade wizard I get a error while upgrading my web app:

 

An error occurred while running the wizard.

Hi Hannes,

The exception suggests that there is an issue upgrading one of the assemblies referenced in the project. Unfortunately, there is not much information altogether, so as a basic troubleshooting I would suggest the following:
  1. Remove all Telerik references from the project(Including Kendo.Mvc)
  2. Perform "Clean Solution" operation
  3. Use the Convert Wizard to try and add the needed assemblies again
  4. Run the Upgrade Wizard

If the above steps do not help can I ask you to send us the problematic project or a sample project with the same behavior so we can further investigate the issue.

Regards,
