As you may already know, we have deprecated classic drivers in the Queens
release. We don't have specific removal plans yet. But according to the
deprecation policy we may remove them at any time after May 1st, which will be
half way to Rocky milestone 2. Personally, I'd like to do it around then.
The `online_data_migrations` script will handle migrating nodes, if all required
hardware interfaces and types are enabled before the upgrade to Queens.
Otherwise, check the documentation  on how to update your nodes.
