Hello,

We are reaching out to let you know that as of December 31, 2024, Amazon Aurora will no longer support Serverless version 1 (v1). As per the Aurora Version Policy [1], we are providing 12 months notice to give you time to upgrade your database cluster(s). Aurora supports two versions of Serverless. We are only announcing the end of support for Serverless v1. Aurora Serverless v2 continues to be supported. We recommend that you proactively upgrade your databases running Amazon Aurora Serverless v1 to Amazon Aurora Serverless v2 at your convenience before December 31, 2024.

Starting on or after 12:00 PM PST on December 31, 2024, if your Amazon Aurora Serverless v1 cluster has not been upgraded, Amazon Aurora will automatically upgrade your Amazon Aurora Serverless v1 cluster to Amazon Aurora Serverless v2 during your next scheduled cluster maintenance window. If your Aurora Serverless v1 cluster is running an engine version that is not available for Aurora Serverless v2, it will be upgraded to an engine version compatible with Aurora Serverless v2.

How to determine which clusters are running Aurora Serverless v1?

You can find information about the DB cluster on the AWS RDS console. Aurora Serverless v1 DB clusters show Serverless for Role in the Summary section of the cluster detail page [2].

Also a list of your affected clusters can be found in the 'Affected resources' tab of your AWS Health Dashboard.

How to Upgrade to Aurora Serverless v2?

You can upgrade your database cluster from Aurora Serverless v1 to Aurora Serverless v2 using the AWS SDK or CLI [3] by following these steps:

* Convert your Aurora Serverless v1 database cluster to a provisioned cluster
* Upgrade the provisioned cluster to the version that is supported with Aurora Serverless v2
* Add a Aurora Serverless v2 reader to the upgraded provisioned cluster and failover to it.

Refer to our Aurora Serverless documentation [3] and also the blog on upgrading from Serverless v1 to Serverless v2 [4].

Please be aware of the following timeline:

- From now through to December 31, 2024 - You can initiate upgrades of Amazon Aurora Serverless v1 to Amazon Aurora Serverless v2 at any time.

- Starting September 1, 2024, you will no longer be able to create new Aurora Serverless v1 clusters or instances with either the AWS Console or the CLI.

- Starting December 31, 2024, Amazon Aurora will upgrade your Aurora Serverless v1 cluster during your next maintenance window to Aurora Serverless v2.

If you have any questions or concerns, please reach out to AWS Premium Support [5].
