After a Subscription instance expires, if renewal has not been completed in the required time, the instance is released automatically. In this case, data is lost permanently and cannot be recovered. To view status changes that occur after Subscription resources expire, see Subscription.

You can use the Renew for Configuration Downgrade function to renew a Subscription instance while also lowering its specifications and reducing costs for the next billing cycle.

You can also change the billing method of your data disks from Subscription to Pay-As-You-Go.

Note

Note the following when using Renew for Configuration Downgrade:

  • The function allows you to scale down instance specifications at the time of renewal.
  • Renew for Configuration Downgrade can only be used for Subscription instances.
  • After you renew an instance, the new package is effective from the next billing cycle. The current package continues until the end of the current billing cycle.
  • If instance configurations are changed during renewal, you must restart the instance within the first seven days of the new billing cycle for the new configurations to be effective. If you restart the instance on the seventh day of the new billing period, the instance is considered to have used the original package for the first six days, and uses the downgraded package only after it is restarted.
  • Once the renewal for configuration downgrade is complete, you cannot upgrade configurations, increase the system disk size, or increase the size of a Subscription data disk, which is attached to a Linux instance or a Windows instance, during the rest of the current billing cycle.
  • You cannot cancel the renewal orders once the payment is processed.

Procedure

To downgrade the configuration of a Subscription instance during renewal, follow these steps:

  1. Log on to the ECS console.
  2. In the left-side navigation pane, click Instances.
  3. Select a region.
  4. Find the Subscription instance. In the Actions column, click Change Configuration.
  5. In the Configuration Change Guide dialog box, select Renew for Configuration Downgrade and click Continue.
  6. On the Renew for Configuration Downgrade page, complete the following operations as necessary:
    • Downgrade Instance Type. If you want to downgrade specifications for an instance, you must also set the Restart Time for that instance.
      Note
      • Instance specifications that can be changed are displayed on the page. For more information about instance specifications, see Instance type families.
      • Restarting an instance suspends your business operations on that instance. Please restart the instance during off-peak hours to reduce impact. The restart must be completed within the first seven days of the next billing cycle. However, you cannot restart an instance during the following periods each week (UTC+8): 12:00 midday Tuesday − 12:00 midday Wednesday, and 12:00 midday Thursday − 12:00 midday Friday.
    • If a data disk was created while creating a Subscription instance, you can change the billing method of the data disk to Pay-As-You-Go.
    • Set the bandwidth value.
    • Set the renewal duration.
  7. Click Pay, and follow the prompts to complete the process.
  8. (Optional) If you have changed instance specifications, or changed the public network bandwidth of an instance in a classic network from 0 Mbit/s to a non-zero value for the first time, you must restart the instance in the console or by using the RebootInstance API within the first seven days of the next billing period. This step is necessary for the new configurations to be effective.
    Note For a VPC instance, the instance does not need to be restarted.
