Data Platforms Reaching End of Life in May and June 2026

Author: Tom Hoblitzell | 6 min read | June 9, 2026

It’s time for some spring cleaning of data platforms – in May 2026, we saw several AWS database versions going end of support for MySQL, PostgreSQL, and MariaDB. Stay on top of all of the data platform end of life dates in our handy calendar.

Data Platforms to Take Action on in May and June 2026

Amazon Aurora MySQL

Amazon Aurora MySQL 3.08 and 3.09, which are compatible with MySQL Community versions 8.0.39 and 8.0.40 respectively, reached their end of standard support date on May 31^st, 2026. Neither minor version is eligible for extended support. Any database instance running one of these versions will be automatically upgraded to the next supported minor version if you have the “Auto minor version upgrade” setting enabled. If this setting is not enabled, you’ll receive a notification in your AWS console notifying you of a scheduled upgrade during the next maintenance window.

Minor versions that are currently still in standard support include Amazon Aurora 3.04 (compatible with MySQL 8.0.28), 3.10 (compatible with MySQL 8.0.42), and 3.11 (compatible with MySQL 8.0.43). Of these, 3.10 has the longest time before its end of standard support, which is April 30^th, 2028.

Amazon Aurora PostgreSQL

Amazon Aurora PostgreSQL 14.13, 14.15, 15.8, and 16.6 all hit their end of life dates in May, and none of them are eligible for extended support. Much like Amazon Aurora MySQL, you’ll be automatically upgraded to the next supported minor version if you have that setting enabled, and will otherwise receive a notification about an upgrade during the next scheduled maintenance window.

Minor versions that are currently still in standard support include 14.6 and 14.17-14.20, 15.10 and 15.12-15.17, and 16.8 -16.11 and 16.13.

Amazon RDS for MariaDB

Rounding out the end of life dates for May for AWS is Amazon RDS for MariaDB, affecting the following minor versions: 10.5.27, 10.6.19–10.6.21, 10.11.9–10.11.11, 11.4.3–11.4.5. As with the Amazon Aurora end of life policies, you’ll go through an automatic upgrade process to a supported minor version.

MariaDB minor versions that are currently supported for each of the deprecated ones include 10.5.28-10.5.29, 10.6.22-10.6.25, 10.11.13-10.11.16, and 11.4.7 to 11.4.10.

Amazon Neptune

Amazon Neptune 1.1.1.0 – 1.2.1.2 are hitting end of life on June 30^th, 2026. These minor versions do not have extended support available, and will be upgraded automatically if you don’t upgrade before the end of June. The upgrade paths that are recommended are:

1.1.0 to 1.2.1.0
2.0.0 – 1.2.1.2 to 1.3.0.0

What’s on the Data Platform End of Life Horizon in July 2026

July is quite an active month for end of life dates.

SQL Server 2016
Amazon RDS for SQL Server 2016
Couchbase Server 7.2
MongoDB 8.2
MariaDB 10.6 Community Support
AWS RDS MariaDB 10.6
Azure Database for PostgreSQL 11, 12, 13
Cloud SQL MySQL 8.0
Azure Database for MySQL 5.7

Data platform end-of-life deadlines are a smart time to reassess whether your current environment still supports the business. Instead of defaulting to an upgrade, consider whether cloud migration or legacy modernization would better position your organization for AI, machine learning, and analytics.

Frequently Asked Questions About Data Platform End-of-Life Management

What does end of support mean for a data platform?

End of support means a database version is no longer receiving standard updates, fixes, or ongoing maintenance from the provider. For example, with AWS managed services, that can also trigger a required upgrade path, either automatically or during a scheduled maintenance window, depending on your configuration.

What should I do if my current database version is reaching end of life?

Start by identifying which environments are affected, then review your upgrade options, application dependencies, and maintenance timing. The goal is to move on your schedule instead of reacting to a forced change that could affect performance, compatibility, or business continuity.

Will AWS automatically upgrade database versions that are no longer supported?

In many cases, yes. AWS documentation indicates that unsupported Aurora minor versions are upgraded to a supported version if automatic minor version upgrades are enabled. If they are not enabled, AWS typically schedules the upgrade during the next maintenance window and notifies you in advance.

Should I upgrade in place, migrate to the cloud, or modernize my platform?

That depends on what the business needs next. An in-place upgrade may be the fastest path to stay supported, but end-of-life events are also a practical time to evaluate whether cloud migration or platform modernization would improve scalability, reduce risk, and better support analytics, AI, and future growth.
