How to upgrade OSS resource plans-Object Storage Service(OSS)-阿里云帮助中心

You can upgrade an OSS resource plan to a higher specification.

Supported upgrades

The following resource plans can be upgraded directly:

Standard (ZRS) storage plan, IA (ZRS) storage plan, Standard (LRS) storage plan, IA (LRS) storage plan, Archive (LRS) storage plan, and Cold Archive (LRS) storage plan
The following resource plans do not support direct upgrades. Instead, purchase multiple plans of the same type to stack capacity.

Outbound data transfer plan, back-to-origin traffic plan, transfer acceleration plan, Request plan (Standard), Request plan (non-Standard), and DDoS Protection Basic plan

Note
Stacking refers to purchasing multiple resource plans of the same type in the same region.

To upgrade resource plans with a RAM user, attach the AliyunBSSOrderAccess policy to grant order management permissions in the User Center. Manage RAM user permissions.
Starting October 24, 2024, upgrades take effect in the next billing cycle (next hour for hourly plans, 00:00 the next day for daily plans). Supplemental fees are calculated from the next cycle. A pending upgrade order blocks renewals, further upgrades, and cancellations until it takes effect.

Upgrade your OSS resource plans. If you use ECS snapshot storage and have not activated OSS, activate OSS first.

Log on to the OSS console.
In the navigation pane on the left, choose Resource Usage > Resource Plans.
On the Resource Plans page, find the target plan and click Upgrade.
On the Upgrade/Downgrade page, select a higher specification, click Buy Now, and complete the payment.

Note
You must select a specification higher than your current one. Upgrades cannot be reversed. For example, a 100 GB plan can only be upgraded to a specification larger than 100 GB.
