This endpoint allows you to migrate one or more subscriptions from an existing recurrence plan (from) to a new target plan (to). This is useful when updating the terms or pricing of an active subscription without interrupting service to the customer.
Usage Scenarios: - Moving existing customers from a legacy plan to a newly structured or updated plan. - Updating subscription pricing or billing frequency while preserving active subscriptions. - Consolidating subscriptions under a single plan for easier management.
Notes: - Both from and to plan IDs must be valid UUIDs and belong to the same seller. - If the subscriptions list is not provided, all subscriptions linked to the source plan (from) will be migrated to the destination plan (to). - The username header should be provided for audit and traceability purposes. - Ensure that the destination plan has compatible settings to avoid issues during migration.
