Install the Latest Service Software Update​

Before starting the update:

  • confirm the domain is healthy and no conflicting configuration changes are in progress;
  • schedule the change during a low-traffic maintenance window;
  • notify application owners if the domain supports production workloads.

From AWS CLI​

Use the following command to start the service software update immediately:

aws opensearch start-service-software-update \
  --domain-name {{domain-name}} \
  --schedule-at NOW

Monitor the domain until the update completes and CloudAware no longer reports Service Software: Update Available as true.

If the request fails because the selected time slot is not available, review the alternate scheduling information returned by AWS and resubmit the update for an available window.
