This section describes how to renew the eSurfing Cloud RDS for MySQL.
Application Scenarios
You can renew a single Annual/Monthly Package instance according to your service requirements, or you can renew multiple Annual/Monthly Package instances by batch.
Constraints and Restrictions
1. After the Payment by Volume database instance stops, it will automatically renew after you recharge the account balance, without manual renewal.
2. After the primary instance is renewed, the read-only instances will not be renewed synchronously.
3. To renew read-only instances, make sure that the validity period of the primary instance is greater than the total validity period of the read-only instances after renewal. Otherwise, the read-only instances cannot be renewed separately. They can be renewed only after the primary instance is renewed.
Procedure
1. Log in to the Console.
2. Click 
in the upper left corner of the Console, and select Region and Project.
3. Select Database > Relational database... Go to the MySQL Console.
4. On the Instance Management page, select the specified instance, click More, and select Renew. Then, go to the Renew page to renew the instance.
5. Select the renewal time on the Renew page and complete the payment.
