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 during the remainder of the current billing cycle.
Prerequisites
- Within 15 days before the instance expires
- After the instance expires but before the instance is automatically released
Background information
When you renew an instance and downgrade its configurations, you can downgrade the
following configurations:
- You can downgrade the instance type.
Note When you perform renewal and configuration downgrade after an instance expires but before the instance is automatically released, you cannot change the instance type.
- You can change the public bandwidth configurations. You can downgrade the public bandwidth or change the billing method to pay-by-traffic and set a peak value for the bandwidth.
- You can change the billing method of data disks from subscription to pay-as-you-go.
When you renew an instance and downgrade its configurations, 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. The original configurations remain unchanged during the remainder of the current billing cycle.
- If you perform the following operations when you renew an instance and downgrade its
configurations, you must restart the instance by using the console or calling the
RebootInstance operation within the first seven days of the new billing cycle to make the new configurations
take effect. The operations include:
- 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.
- If you perform renewal and configuration downgrade for an instance before it expires,
you cannot perform the following operations during the remainder of the current billing
cycle:
- Upgrade the instance type.
- Temporarily upgrade the public bandwidth.
- Resize disks, including the partitions and file systems.
Procedure
- Log on to the ECS console.
- In the left-side navigation pane, choose .
- In the top navigation bar, select a region.
