When you run the migration script for the first time, it checks for the prerequisites and proceeds with the migration. If all prerequisites are met, the migration completes without any errors. If any prerequisite fails, the script displays error messages with reasons. After fixing the errors, you must rerun the script again.
If you see an error message that displays “already exists”, it means that:

You might have run the migration script for more than one time and some configurations are already migrated to ADM service.
-
You might have manually created the same configuration in ADM service, before running the migration script.
