Database versions and version policies

This page describes Cloud SQL's database version support policies.

Major and minor versions supported by Cloud SQL

Cloud SQL supports the following database versions:

Major versionMinor version

SQL Server 2022 EnterpriseCU7
SQL Server 2022 ExpressCU7
SQL Server 2022 WebCU7

Cloud SQL automatically keeps your instances up to date with patches and minor version updates.

As indicated in the previous table, the database engines supported by Cloud SQL include multiple versions. The versions can vary in their functionality and in the types of issues that arise. While Cloud SQL recognizes that upgrades impact users, we are committed to providing up-to-date functionality and important patches.

Major and minor versions

For SQL Server, the date forms the major version number.

Major version support

Cloud SQL aims to support new major versions within five months of general availability release by the database engine developer.

Minor version support

Cloud SQL aims to support new minor versions within three months of general availability release by the database engine developer.

Major version deprecation plan

When Cloud SQL intends to end support for a specific major version, we will send a deprecation notice alerting project owners a minimum of 12 months ahead.

Cloud SQL will also provide tools to minimize upgrade disruption, as needed. Any instance that has not moved to the new major version at the end of the 12-month period will be automatically upgraded.
