Aurora Serverless v1 and Aurora database engine versions

Important

Amazon has announced the end-of-life date for Aurora Serverless v1: March 31st, 2025. We strongly recommend upgrading any Aurora Serverless v1 DB clusters to Aurora Serverless v2 before that date. The upgrade can involve a change in the major version number of the database engine. Thus, it's important to plan, test, and implement this switchover before the end-of-life date. Starting January 8th, 2025, customers will no longer be able to create new Aurora Serverless v1 clusters or instances with either the Amazon Web Services Management Console or the CLI. For information about the migration process, see Upgrading from an Aurora Serverless v1 cluster to Aurora Serverless v2.

Aurora Serverless v2 scales more quickly and in a more granular way. Aurora Serverless v2 also has more compatibility with other Aurora features such as reader DB instances. You can learn about Aurora Serverless v2 in Using Aurora Serverless v2.

Aurora Serverless v1 is available in certain Amazon Web Services Regions and for specific Aurora MySQL and Aurora PostgreSQL versions only. For the current list of Amazon Web Services Regions that support Aurora Serverless v1 and the specific Aurora MySQL and Aurora PostgreSQL versions available in each Region, see Aurora Serverless v1.

Aurora Serverless v1 uses its associated Aurora database engine to identify specific supported releases for each database engine supported, as follows:

  • Aurora MySQL Serverless

  • Aurora PostgreSQL Serverless

When minor releases of the database engines become available for Aurora Serverless v1, they are applied automatically in the various Amazon Web Services Regions where Aurora Serverless v1 is available. In other words, you don't need to upgrade your Aurora Serverless v1 DB cluster to get a new minor release for your cluster's DB engine when it's available for Aurora Serverless v1.

Aurora MySQL Serverless

Aurora Serverless v1 is available in certain Amazon Web Services Regions and for specific Aurora MySQL versions only. For the current list of Amazon Web Services Regions that support Aurora Serverless v1 and the specific Aurora MySQL versions available in each Region, see Aurora Serverless v1 with Aurora MySQL.

Minor releases for Aurora PostgreSQL-Compatible Edition include only changes that are backward-compatible. Your Aurora Serverless v1 DB cluster is transparently upgraded when an Aurora PostgreSQL minor release becomes available for Aurora Serverless v1 in your Amazon Web Services Region.

To use a more recent version of Aurora PostgreSQL, you can use Aurora Serverless v2. For the Amazon Web Services Regions and Aurora PostgreSQL versions that you can use with Aurora Serverless v2, see Aurora Serverless v2 with Aurora PostgreSQL.
