You can configure auto-renewal for a simple application server when you create the server. You can also manually renew the server after you create the server. If the configurations of your simple application server can no longer meet your business requirements, you can upgrade your server. This topic describes how to upgrade and manually renew your simple application server.
Background information
A simple application server automatically stops 15 days after it expires. The data on the server is retained for another 15 days from the moment the server stops. You can start the server after you renew it within the 15-day period of time. If you fail to renew the server within the 15-day period of time, the server and the snapshots and custom images that are created based on the server are released. The data cannot be recovered.
For more information, see Expiration and overdue payments.
Upgrade a simple application server
We recommend that you create snapshots for the disks of your simple application server to back up data before you upgrade the server. For more information, see the Create a snapshot.
Creating snapshots requires a period of time. Wait until the snapshots are created.
When you upgrade the server, the system calculates the price difference between the original and new plans. To upgrade the server, you must pay this difference. For more information, see Upgrade a simple application server.
Simple application servers cannot be downgraded.
