Description
We have identified one or more OpenSearch Service domains in your account that are either currently using an engine version under Extended Support or are projected to enter Extended Support within the next year. OpenSearch Extended Support is a paid offering that results in significant additional costs. Upgrading these domains to a current supported engine version eliminates or prevents those charges.
Selection Criteria
The OpenSearch domain is currently using a version under Extended Support.
OR the OpenSearch domain is using a version that will enter Extended Support within the next year.
Expected Saving
OpenSearch Extended Support costs $0.012/OCU/hour on top of standard domain costs. The exact amount depends on domain size and instance type. Upgrading to a supported version eliminates this surcharge entirely.
Operational Impact
Downtime: OpenSearch version upgrades are applied via a blue/green deployment. The domain remains available but performance may be reduced during the upgrade, which can take several hours depending on cluster size and shard count.
⚠️ Warning — Breaking changes: Major version upgrades (e.g., OpenSearch 1.x → 2.x) may introduce query syntax or API compatibility changes. Validate application behavior against the new version before upgrading production.
⚠️ Warning — Upgrade path: Some versions require intermediate upgrades before reaching the latest supported version. Verify the full supported upgrade path before proceeding.
⚠️ Warning — Blue/green deployment: Other cluster configuration changes are blocked during the upgrade process until it completes.
