This topic describes how to renew an instance and upgrade or downgrade the configuration of an instance in the Message Queue for MQTT console.

Background information

If you upgrade or downgrade the configuration of an instance, the changes take effect in the current subscription period. If you renew an instance, the changes take effect in the next subscription period.

Limits

Instance renewal, upgrades, and downgrades are applicable only to subscription instances. These operations are not supported for pay-as-you-go instances.

Renew an instance

A notification will be sent to the mobile number that is specified within your Alibaba Cloud account seven days before a subscription instance expires. When you receive this notification, renew the instance in time. If this instance is not renewed upon expiration, it is retained for 30 days. After 30 days, the instance and relevant resources such as topics and groups are automatically deleted and cannot be recovered.

Enable auto-renewal (Recommended)

If you need to use a service for a long time, you can enable the auto-renewal feature. After the auto-renewal feature is enabled, the system performs auto-renewal before your resources expire to ensure that your resources and data are not deleted. This also prevents your business from being affected.

  1. Log on to the Message Queue for MQTT console. In the top navigation bar, choose Expenses > Renewal Management.
  2. On the Renewal page, select AliwareMQ for IoT in the Instances section. Select the region from the Region drop-down list.
  3. Click the Manual tab. Find the instance for which you want to enable auto-renewal and click Enable Auto Renewal in the Actions column.
  4. In the Enable Auto Renewal dialog box, set the Unified Auto Renewal Cycle parameter and click Auto Renew.

Manually renew an instance

If you need to continue using Message Queue for MQTT but auto-renewal is not enabled for your instance, you can manually renew the instance before it expires.

  1. Log on to the Message Queue for MQTT console.
  2. In the left-side navigation pane, click Instances.
  3. In the top navigation bar, select a region.
  4. In the instance list, find your instance and click the name of the instance or click Details in the Actions column.
  5. In the Overview section of the Instance Details page, click Renew.
  6. On the Renew page, select a renewal period, select Alibaba Cloud Message Queue for MQTT Terms of Service, and then click Buy Now.
  7. On the Purchase page, click Purchase and complete the payment.

Upgrade or downgrade the configuration of an instance

You can upgrade or downgrade the configuration of an instance to meet your business needs without service disruption.
Notice
  • Upgrades on Basic Edition instances immediately take effect. Upgrades on Enterprise Platinum Edition instances may require help from a technical support engineer of Message Queue for MQTT. This may increase the amount of time required for the upgrade to take effect. During this period, your instance is not affected and can continue to provide services.
  • Instance downgrades immediately take effect. Refunds are not given for instance downgrades. Therefore, we recommend that you downgrade the configuration of an instance at the end of the billing cycle of the instance.
  • You cannot upgrade or downgrade the service edition of an instance. For example, you cannot upgrade an instance of Basic Edition to Enterprise Platinum Edition or downgrade an instance of Enterprise Platinum Edition to Basic Edition.
  1. Log on to the Message Queue for MQTT console.
