Amazon OpenSearch Service extends version lifecycle support timelines

In November 2024, we announced Standard and Extended Support dates for legacy Elasticsearch versions (1.5 through 7.8) and OpenSearch versions (1.0 through 1.2, and 2.3 through 2.9) running on Amazon OpenSearch Service. At that time, Extended Support for these versions was set to end on November 7, 2026 (except Elasticsearch 5.6, for which Extended Support ends on November 7, 2028), after which domains would no longer receive security fixes or operating system patches.

Since that announcement, many customers have upgraded to newer versions. However, some customers need more time to plan and complete their migrations. To provide this flexibility, we are continuing security and operating system patch coverage for these versions for an additional 12 months, through November 7, 2027, at an updated support rate.

Today, we’re announcing two updates: Extended Support extension for present versions and End of Standard Support and Extended Support for additional versions.

Extended Support extension for present versions

We are continuing security and operating system patch coverage for Elasticsearch versions 1.5 through 7.8, OpenSearch versions 1.0 through 1.2, and OpenSearch versions 2.3 through 2.9 for an additional 12 months. Coverage will now continue through November 7, 2027, giving customers additional time to plan and execute their migrations to the latest OpenSearch versions.

From November 7, 2026, the Extended Support surcharge for these versions will effectively double your instance pricing for the extension period. Storage costs are not affected. Elasticsearch 5.6, for which existing Extended Support rates end on November 7, 2028, will continue at the standard Extended Support cost of $0.0065 per Normalized Instance Hour (NIH). During this period, these versions will continue to receive critical security patches and operating system updates.

See the following table for the updated Extended Support end dates.

We recommend that you upgrade to the latest available OpenSearch version.

End of Standard Support and Extended Support for additional versions

Today we are announcing end of Standard and Extended Support dates for Elasticsearch versions 6.8, 7.9, and 7.10, OpenSearch version 1.3, and OpenSearch versions 2.11 to 2.19. For future updates on versions in Standard Support and Extended Support, follow supported versions.

For OpenSearch versions running on Amazon OpenSearch Service, we provide at least 12 months of Standard Support after the end-of-support date for the corresponding upstream open source OpenSearch version. Alternatively, we provide 12 months of Standard Support after the release of the next minor version on Amazon OpenSearch Service, whichever is longer. This aligns with the open source OpenSearch maintenance policy.

We categorize these versions into two groups:

• The last versions of each major version family (ES 6.8, ES 7.10, OS 1.3, OS 2.19) will receive 3 years of Extended Support at the standard Extended Support charge of $0.0065 per NIH.
• All other minor versions with clear upgrade paths within the same major family (ES 7.9, OS 2.11, OS 2.13, OS 2.15, OS 2.17) will receive 1 year of Extended Support at the same standard rate of $0.0065 per NIH.

After Extended Support ends for a version, domains running that version will not receive bug fixes or security updates. The following table shows the end of Standard Support and Extended Support dates for Elasticsearch and OpenSearch versions.

OpenSearch versions

Upgrading OpenSearch Service domains: We recommend that you upgrade your domains to the latest available OpenSearch version to derive maximum value out of Amazon OpenSearch Service. Minor version upgrades on OpenSearch don’t contain breaking changes. These version upgrades are typically non-disruptive. We recommend moving to the latest minor version. See Upgrading OpenSearch Service domains for detailed instructions. You can also use the Migration Assistant for Amazon OpenSearch Service for upgrading to newer versions.

New domain creation: New domain creation will be blocked after Extended Support ends for each version.

Calculating Extended Support charges

Amazon OpenSearch Service domains running versions under Extended Support will be charged a flat additional fee per NIH. NIH is computed as a factor of the instance size (for example, medium or large), and the number of instance hours.

Depending on which version you are on, the Extended Support charges are as follows:

• Versions that have been on Extended Support (ES 1.5–7.8 (other than ES 5.6), OS 1.0–1.2, OS 2.3–2.9) from November 7, 2026: Extended Support cost will be equal to your instance price. This will be in addition to the standard instance pricing, effectively doubling the instance cost. Storage costs are not affected. Example (for versions that have been on Extended Support from November 7, 2026): If you are running an m7g.medium.search instance priced at $0.068/hr (on-demand) in US East (N. Virginia) for 24 hours, your standard instance cost is $1.632/day ($0.068×24). The Extended Support surcharge for the extension period will be equal to your instance cost ($1.632/day), doubling your instance pricing to ~$3.264/day. Storage costs remain unchanged.
• New versions coming under Extended Support (ES 6.8, 7.9, 7.10, OS 1.3, OS 2.11–2.19): $0.0065 per NIH (standard Extended Support rate). See the pricing page for exact pricing by Region. Example (new versions — standard rate): If you are running an m7g.medium.search instance for 24 hours in the US East (N. Virginia) Region, priced at $0.068 per instance hour (on-demand), you will typically pay $1.632 ($0.068×24). If you are running a version that is in Extended Support, you will pay an additional $0.0065 per NIH. This is computed as $0.0065 × 24 (instance hours) × 2 (normalization factor for medium) = $0.312 for Extended Support for 24 hours. The total amount you will pay for 24 hours is $1.944 ($1.632 + $0.312, excluding storage cost).

The following table shows the normalization factor for various instance sizes in OpenSearch Service.

Summary

The latest OpenSearch versions include new features, performance and resiliency improvements, and security enhancements. With today’s announcement, we are:

• Continuing security and operating system patch coverage for present versions through November 7, 2027, giving customers additional time to complete their upgrades at a new Extended Support rate.
• Announcing Standard and Extended Support timelines for the next set of versions (ES 6.8, 7.9, 7.10, OS 1.3, 2.11–2.19) with predictable cost visibility.

We recommend that you upgrade to the latest OpenSearch versions to get the most benefit out of OpenSearch Service. For any questions on Standard and Extended Support options, see the FAQs. For further questions, contact AWS Support.
