Note:
Storage packs can be upgraded, while traffic packs and request packs cannot. To upgrade a traffic pack or request pack, you need to purchase a new one at Pricing | Cloud Object Storage. Multiple traffic packs or request packs can be used together. A previously purchased resource pack whose price has changed (for example, price reduction) can no longer be upgraded, and you need to purchase a new one at Pricing | Cloud Object Storage. COS allows you to upgrade a resource pack. If the specification of an existing resource pack no longer meets your actual business needs, click Upgrade to upgrade the specification.
The upgrade steps are as follows:
2. On the left sidebar, click Resource Packs to enter the resource pack management page.
3. Select an existing resource pack and click Upgrade.
4. In the pop-up window, select the new specification, click Upgrade, and follow the on-screen instructions to complete your purchase.
