Upgrade a file gateway - Cloud Storage Gateway - Alibaba Cloud Documentation Center

This topic describes how to upgrade a file gateway in the Cloud Storage Gateway (CSG) console.

Prerequisites

A file gateway has been created. For more information, see Create a file gateway.

Background information

If the current specification of your gateway no longer meets your business requirements, you can upgrade it. A higher specification provides increased read/write bandwidth, supports more shares, and offers additional features.

Warning

Upgrading gateway specifications will cause temporary business interruptions. Exercise caution when performing this action.

Table 1. Gateway upgrade paths

Specification	Basic	Standard	Enhanced	Performance optimized
Basic	N/A	✓	✓	✓
Standard	×	N/A	✓	✓
Enhanced	×	×	N/A	✓
Performance Optimized	×	×	×	N/A

Note

The check mark (✓) indicates you can upgrade to the corresponding specification. The cross mark (×) indicates you cannot.
You can upgrade only online gateways.
You can upgrade gateways, but downgrading is not supported.
Available upgrade specifications depend on resource availability in the gateway's zone.

Procedure

In the Cloud Storage Gateway console, go to the Gateways page. Find the target gateway, and on the right, click More.
In the Upgrade Gateway dialog box, select the target specification and click OK. The gateway then begins to upgrade.
Note
- The upgrade can be time-consuming and will interrupt services. You may need to remount your shares after the upgrade is complete. We recommend performing this operation during a planned maintenance window.
- You can monitor the progress and status of the upgrade task in the task list at the bottom of the Shares page.
