    Earlier I have developed website in 3.7. now I want to upgrade into 4.2. but I am facing some problem during migration.

    I followed the step to setup migration process

    1. Step 1: Copy the .dll and .svc files. Details
    2. Step 2: Edit the web.config and add the snippet before the last </configuration> tag. Details
    3. Step 3: Enter the 3.7 Standart edition project URL in the field (on the left)
    4. Step 4: Select the content you want to migrate and click Begin Migration

    but when I trying to access http://localhost:50722/oldwebsite/MigrationService.svc, page is displaying

    Could not load file or assembly 'Telerik.Sitefinity.Migration' or one of its dependencies. This assembly is built by a runtime newer than the currently loaded runtime and cannot be loaded.

    and when I copy the URL to setup migration, the result is

    Migration Log

    "Error: Could not find http:\/\/localhost:50722\/oldwebsite\/MigrationService.svc on the source site. Error details:An error occurred while receiving the HTTP response to http:\/\/localhost:50722\/oldwebsite\/MigrationService.svc. This could be due to the service endpoint binding not using the HTTP protocol. This could also be due to an HTTP request context being aborted by the server (possibly due to the service shutting down). See server logs for more details.
    Migration stopped.

    I have spent more than a week on this to get solution.

    Hello Joshua,

    Looks like you haven't copied the Telerik.Sitefinity.Migration.dll to the bin folder of your Sitefinity 3.7 project. Please check the installation guide here:
