Changing Billing Mode

To change the edition of a DBSS instance, unsubscribe from it and purchase a new one.
Unsubscription: To stop using DBSS, go to the Billing Center to unsubscribe from it.

Renewal

If you do not renew a DBSS instance that is billed in yearly/monthly mode upon its expiration, a retention period will be granted.

A DBSS instance stops providing services when it expires. To avoid loss caused by security issues, you are advised to renew it in a timely manner. DBSS expiration does not affect your other services.

You can renew your resources on the Renewals page of the management console. For details, see Renewal Management.
