You can upgrade the version of a Microservices Engine (MSE) cloud-native gateway.
-
Gateway upgrades do not affect short-lived connections. However, persistent connections such as WebSocket or gRPC connections may be briefly disconnected. If your gateway relies heavily on persistent connections, we recommend that you perform the upgrade during off-peak hours.
-
For standalone instances earlier than V1.2.11, short-lived connections are disconnected during the upgrade. For V1.2.11 and later, short-lived connections are not affected.
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 to upgrade and click Manual Upgrade in the Version column. In the Gateway Version Upgrade dialog box, click OK.
The upgrade takes about 5 to 10 minutes.
