# Amazon Aurora PostgreSQL: PostgreSQL 11 end of RDS Extended Support

## What breaks

End of RDS Extended Support date for this major version: 31 Mar 2027. RDS Extended Support is the paid offering that allows a database to keep running a major version past its Aurora end of standard support date. After RDS Extended Support ends, Aurora automatically upgrades the major engine version of any database that has not been upgraded to a supported version.

- AWS recommends upgrading to a supported major engine version.
- New major PostgreSQL versions might contain database changes that are not backward-compatible with existing applications.

## Who is affected

### Affected versions

- `11`

### Matching resource types

- `aws_rds_cluster`

### Fields the check reads

- `engine`
- `engine_version_actual`
- `engine_version`

### Detected by the estate check from

- Terraform state or plan (JSON)

## What to do

1. Test the upgrade first by following [Testing an upgrade of your production DB cluster to a new major version](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/USER_UpgradeDBInstance.PostgreSQL.MajorVersion.html#USER_UpgradeDBInstance.PostgreSQL.MajorVersion.Upgrade.preliminary), so that you know your applications can run on the new version.
2. Manually upgrade the Aurora PostgreSQL DB cluster to the new major version. See [Performing a major version upgrade](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/USER_UpgradeDBInstance.PostgreSQL.MajorVersion.html).
3. Run the upgrade during the cluster's maintenance window or when operations are minimal, because a brief outage is possible.
4. If an immediate switchover matters most, run the old and new clusters side by side with [Amazon Aurora Blue/Green Deployments](https://docs.aws.amazon.com/AmazonRDS/latest/AuroraUserGuide/blue-green-deployments.html).

## Replacement

Not stated by vendor.
