This topic describes how to downgrade the configurations of a subscription instance when you renew the instance. The new configurations take effect starting from the next billing cycle. The original configurations remain unchanged for the rest of the current billing cycle.

Background information

You can use the renewal and configuration downgrade feature to complete the following tasks:
  • Downgrade the instance type of a subscription instance.
  • Change the billing method of data disks from subscription to pay-as-you-go.
  • Change the billing method for Internet usage.
  • Adjust the public bandwidth.
When you use the renewal and configuration downgrade feature, take note of the following items:
  • After the instance is renewed and its configurations are downgraded, the new configurations take effect starting from the next billing cycle. Current configurations continue until the end of the current billing cycle.
  • If you perform the following operations during the renewal and configuration downgrade, you must restart the instance within the first seven days of the next billing cycle for new configurations to take effect. If you restart the instance on the seventh day of the new billing cycle, the instance continues to use the original configurations for the first six days.
    Notice To restart an ECS instance, you must use the ECS console or call the RebootInstance operation. You cannot restart an instance from within the operating system.
    • Change the instance type.
    • Change the public bandwidth value of a classic network-type instance from 0 Mbit/s to a non-zero value for the first time.
  • After you renew an instance and downgrade the instance configurations, you cannot perform the following operations within the rest of the current billing cycle:

Procedure

  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. Find the target subscription instance. In the Actions column, click Upgrade/Downgrade.
  5. In the Upgrade/Downgrade Wizard dialog box, select Renewal and Downgrade and click Continue.
  6. On the Renewal and Downgrade page, complete the following operations:
    1. Select an instance type.
      The instance types to which you can downgrade the instance type of the target instance are displayed on the page.
    2. Set the instance restart time.
      This setting is required only when you change instance types. The restart time cannot be later than the seventh day of the next billing cycle. We recommend that you set the restart time to a point in time during off-peak hours.
    3. Optional:Set public bandwidth.
      Current billing method Supported operation
      Pay-By-Bandwidth
      • Reduce the bandwidth value.
        Reducing the bandwidth value to 0 Mbit/s has the following impacts on public IP addresses:
        • For classic network-type ECS instances, public IP addresses will not be changed.
        • For VPC-type ECS instances, public IP addresses are released when the next billing cycle begins.
      • Change the billing method to Pay-By-Traffic and set the peak bandwidth.
      Pay-By-Traffic You can set the peak bandwidth.
    4. Optional:Change the billing method of data disks from subscription to pay-as-you-go.
      If the billing method does not change, the data disks and the instance will have the same billing cycle starting on the next billing cycle.
    5. Set the renewal duration.
  7. Select ECS Service Terms, and then click Create Order.
  8. Complete the payment.
