Hello,
Do you mean you want to skip the migration? We highly recommend you to migrate your resource if you haven't done it. As of December 3rd 2020, existing LUIS users must have completed the migration process to continue authoring LUIS applications.
Please refer to following documentation for more details about the process. It's not complicated.
