Scenario
Tencent Cloud CVM allows you to switch the instance billing mode from monthly subscription to pay-as-you-go. This document describes how to do it in the CVM console.
Note
The monthly subscribed instances in shutdown status will be retained after they are switched to pay-as-you-go instances, and they will continue to incur fees. You can enable the "No Charge when Shut Down" feature for the instances to save costs. For more information, see Enabling No Charge when Shut Down for a pay-as-you-go instance.
For monthly subscribed instances purchased at a special offer price, if you switch them to pay-as-you-go and then back to monthly subscription, the special offer will not be available.
Switching rules
The CVM console allows you to switch the billing mode based on the following rules:
You can switch the billing mode of one or multiple CVM instances at a time.
Monthly bandwidth can be switched to traffic-based billing. However, bandwidth packages and EIPs of Standard Account Type cannot be switched.
The billing mode of the elastic cloud disks and mounted local disks is changed to pay-as-you-go along with the monthly subscribed instance.
Expired cloud disks cannot be switched; you need to renew or detach them first. Instances with non-elastic data cloud disks cannot be switched from monthly subscription to pay-as-you-go.
The new billing period of a changed CVM instance starts the moment when the billing mode is changed.
Usage Limits
If the remaining quota of pay-as-you-go instances for the zone is less than the number of monthly-subscribed instances to be changed, the billing mode cannot be changed. In this case, you must increase instance purchase quota before changing the billing mode.
You can change only monthly-subscribed instances.
A monthly-subscribed instance with an unpaid renewal order cannot be changed.
