This topic describes how to upgrade the version of a Microservices Engine (MSE) cloud-native gateway.
The gateway upgrade has no negative impact on short-lived connections. During the gateway upgrade, persistent connections may be disconnected and reconnected. If your gateway has many persistent connections that comply with Websocket or gRPC, we recommend that you upgrade your gateway during off-peak hours.
For standalone instances in versions earlier than V1.2.11, short-lived connections are disconnected during the upgrade. For standalone instances in version V1.2.11 or later, short-lived connections are not disconnected during the upgrade.
Prerequisites
Version upgrade
Log on to the MSE console. In the top navigation bar, select a region.
In the left-side navigation pane, choose Cloud-native Gateway > Gateways.
On the Gateways page, find the gateway that you want to upgrade and click Manual Upgrade in the Version column. In the Gateway Upgrade dialog box, click OK.
The upgrade process takes about 5 to 10 minutes.
