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
- Step 1: Copy the .dll and .svc files.
- Step 2: Edit the web.config and add the snippet before the last
</configuration> tag. Details
- Step 3: Enter the 3.7 Standart edition project URL in the field (on the left)
- 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
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.
I have spent more than a week on this to get solution.
