If you have multiple subscription instances that expire on different dates, you can synchronize their expiration dates to the same day of the month to simplify management and renewal.

Background information

Synchronized expiration dates are expressed in the format of Day x of Each Month 00:00, which indicates that instances may expire at 00:00:00 on Day x of the month. For example, assume that you have multiple subscription instances that were to expire on January 1, 2022, February 10, 2022, and March 20, 2022. After you synchronize their expiration dates to Day 1 of the month, you need only to renew instances prior to Day 1 of the month, without the need to record multiple expiration dates.
Note Subscription instances whose expiration dates are synchronized are renewed once to the specified day of the month, but do not have auto-renewal enabled. For information about how to enable auto-renewal for an instance, see Enable auto-renewal for an instance.
When you synchronize the expiration dates of subscription instances, take note of the following limits:
  • The interval between the expiration date of the current billing cycle and the synchronized expiration date cannot be less than one month.

    If the interval is less than one month, instances are renewed on the first synchronized expiration date after 30 days. The renewal prices of instances during this period are calculated based on the pricing standard of a monthly subscription. For more information, see the Pricing tab on the Elastic Compute Service product page.

    Assume that you have two subscription instances that were originally set to expire on September 10, 2018 and May 17, 2018. You synchronize their expiration dates to the first day of each month. The two instances are now set to expire on November 1, 2018 and July 1, 2018.

  • This feature is applicable only to subscription ECS instances that have not expired.

    If one of the selected instances has expired, the expiration dates cannot be synchronized. To synchronize the expiration dates, remove or manually renew the expired ECS instance first.


  1. Log on to the ECS console.
  2. In the left-side navigation pane, choose Instances & Images > Instances.
  3. In the top navigation bar, select a region.
  4. Select the instances whose expiration dates you want to synchronize.
  5. In the lower part of the Instances page, choose More > Instance Settings > Synchronize Expiration Date.
  6. On the Synchronize Expiration Date page, complete the settings.
    1. Confirm the information of the selected subscription instances.
      Confirm the renewal cycle and cost of each instance. If one of the selected instances has expired, no cost information is displayed in the Price column corresponding to the instance. Perform one of the following operations on the expired instance before you proceed:
      • Click Remove in the Actions column corresponding to the expired instance.
      • Go back to the Instances page to manually renew the expired instance and then synchronize the expiration dates of instances. For more information, see Manually renew an instance.
    2. In the Synchronize Expiration Date section, click Set Synchronized Expiration Date.
      Note By default, the synchronized expiration date is 00:00:00 on Day 1 of the month in UTC+8. Pay attention to your time zone. If you want to use the default synchronized expiration date or if you have set a synchronized expiration date, skip this step.
    3. In the ECS Instances: Set Unified Expiration Date dialog box, select a date and click OK.
      ECS Instances: Set Unified Expiration Date
    4. Go back to the Synchronize Expiration Date page and click the refresh icon.
