Switch to subscription billing to reduce costs on ApsaraDB for MongoDB instances with stable, long-running workloads.
Prerequisites
Before you begin, ensure that:
The instance uses pay-as-you-go billing and is in the Running state
The instance is of an available instance type. If it uses an unavailable (historical) instance type, change the instance type first
The instance runs MongoDB 4.0 or later. If the version is earlier than 4.0, upgrade the major version or minor version first
The instance has no unpaid subscription orders. Switching to subscription generates a new order. Until that order is paid or cancelled, you cannot purchase new instances or switch other instances to subscription. To manage pending orders, go to Expenses and Costs
Your Alibaba Cloud account has enough balance to cover the subscription fee
Usage notes
A subscription instance cannot be released.
