Upgrading Major Versions in Zero Downtime
This section explains the steps to upgrade API Gateway in zero downtime for major versions like 10.5 to 10.7, 10.7 to 10.11, and so on.
Prerequisites
The minimum version of the
API Gateway instance that is being upgraded to a higher version (10.7, 10.11, and so on) must be version 10.5. The target
API Gateway instance version can be 10.7 and above.
Ensure that the old
API Gateway instance is running.
Create a quiesce port in old
API Gateway instance. If you are using a cluster setup, you must create a quiesce port for each
API Gateway instance in the old instance. To learn more about quiesce port, see
API Gateway
Quiesce Mode.
