[Announcement] Support for Aurora Serverless v1 ending soon
Amazon Aurora Serverless version 1 (v1) deprecation has been extended from December 31, 2024, to March 31, 2025.
Amazon Aurora supports two versions of Serverless: Aurora Serverless v1 and Aurora Serverless version 2 (v2) [1] . This end-of-support announcement applies only to Serverless v1. Aurora Serverless v2 continues to be supported and now offers additional features such as support for DataAPI, automatic pause/resume capabilities, and a maximum database capacity of up to 256 ACUs. This allows you to seamlessly migrate your applications that rely on these capabilities to Aurora Serverless v2. We recommend proactively upgrading your databases running Aurora Serverless v1 to Aurora Serverless v2 before March 31, 2025. Please note that Amazon RDS Extended Support will not be available for Aurora Serverless v1.
Starting on or after April 7, 2025, if your Aurora Serverless v1 cluster has not been upgraded, Amazon Aurora will automatically upgrade your Aurora Serverless v1 cluster to Aurora Serverless v2 during a 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 supported by Aurora Serverless v2.
How do I determine which of my clusters are running Aurora Serverless v1?
You can find information about the DB cluster on the RDS console. Aurora Serverless v1 DB clusters show Serverless for Role in the Summary section of the cluster detail page. Refer to our documentation for detailed steps [2].
Additionally, a list of your affected resources is available in the "Affected resources" tab of your AWS Health Dashboard.
How do I upgrade my clusters 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.
- If necessary, upgrade the provisioned cluster to an engine version that is supported by Aurora Serverless v2 [4].
- Add an Aurora Serverless v2 reader to the upgraded provisioned cluster and failover to it.
Refer to our documentation [3,6] and also this blog article about upgrading from Serverless v1 to Serverless v2 [5].
Summary of Important Dates:
- Now through March 31, 2025, You can initiate upgrades of Aurora Serverless v1 to Aurora Serverless v2 at any time.
- Starting January 8, 2025, you will no longer be able to create new Aurora Serverless v1 clusters with either the AWS Console or the CLI.
- On or after April 7, 2025, Amazon Aurora will upgrade your Aurora Serverless v1 cluster during your next maintenance window to Aurora Serverless v2. In case of upgrade failure, we will convert the Serverless v1 cluster to a provisioned cluster in the equivalent engine version, and if applicable, that provisioned cluster will be subject to Amazon RDS Extended Support (see the RDS User guide for more information about Extended Support) [7].
If you have any questions or concerns, the AWS Support Team is available on AWS re:Post and via Premium Support [8]

Amazon Aurora Serverless v1 is approaching its end-of-life date, which has been extended to March 31, 2025. AWS strongly recommends that customers upgrade their Aurora Serverless v1 DB clusters to Aurora Serverless v2 before this date. This upgrade is important as it may involve changes in the major version number of the database engine.
Key points to note:
-
Starting January 8, 2025, customers will no longer be able to create new Aurora Serverless v1 clusters or instances using either the AWS Management Console or the CLI.
-
Aurora Serverless v2 offers several advantages over v1, including faster and more granular scaling, and greater compatibility with other Aurora features such as reader DB instances.
-
The upgrade process from Aurora Serverless v1 to v2 involves several steps:
- Convert the Aurora Serverless v1 DB cluster to a provisioned cluster
- If necessary, upgrade the provisioned cluster to an engine version supported by Aurora Serverless v2
- Add an Aurora Serverless v2 reader to the upgraded provisioned cluster and failover to it
-
If customers don't upgrade their Aurora Serverless v1 clusters by the end-of-life date, AWS will automatically upgrade them to Aurora Serverless v2 during a scheduled maintenance window on or after April 7, 2025.
-
In case of upgrade failure, AWS will convert the Serverless v1 cluster to a provisioned cluster in the equivalent engine version.
It's crucial for customers to plan, test, and implement this switchover well before the end-of-life date to ensure a smooth transition and to take advantage of the improved features and performance of Aurora Serverless v2.
