fix: migrate command failure should be handled correctly

In case migrate command fails to migrate the project, currently it shows some generic message without saying what is the actual error. Also the command exits with code 0, which is indication it had succeeded.
Fix this by failing with more descriptive error message and exit code that is not 0.
