Discontinue Auto-Renewable Subscriptions and migrate users to an already existing Full Subscription

Currently, we have multiple subscriptions in our application, each unlocks a specific part of the app and also a Full Subscription which consists of all the features. We are trying to migrate into a single subscription app in the future, that is just a Full Subscription. It's a little unclear how the process of the migration should be. Currently, our plan is as follows.

  1. Remove the options inside the application where the user can purchase the subscriptions and show only the Full Subscription option.
  2. Release the app so future users can only subscribe to the Full Subscription. Existing users will still renew their subscriptions and still see the specific part.
  3. Promote the Full Subscriptions so the other subscribers will be motivated to purchase the Full Subscription.
  4. Remove unwanted subscriptions from sale 3 to 4 months later from AppStoreConnect.

I want to know whether this approach is safe with Apple guidelines. If not what should I change in the approach?

Thanks
