Cumulative updates (CU)

• Each new CU contains all the fixes that were included with the previous CU for the installed version of SQL Server.
• SQL Server CUs are certified to the same levels as service packs, and should be installed at the same level of confidence.
• We recommend ongoing, proactive installation of CUs as they become available according to these guidelines:
  • Historical data shows that a significant number of support cases involve an issue that has already been addressed in a released CU.
  • CUs may contain added value over and above hotfixes. This includes supportability, manageability, and reliability updates.
• We recommend that you test SQL Server CUs before you deploy them to production environments.

When you deploy an update to a hybrid environment (such as Always On, replication, cluster, and mirroring), we recommend that you refer to the following articles before you deploy the update:

• Upgrade a failover cluster instance

  Note

  If you don't want to use the rolling update process, follow these steps to apply an update:

  • Install the update on the passive node.
  • Install the update on the active node (requires a service restart).

• Upgrade and update of availability group servers that use minimal downtime and data loss

  Note

  If you enabled Always On together with the SSISDB catalog, see the information about SSIS with Always On about how to apply an update in these environments.

SQL Server CUs are currently multilingual. Therefore, this CU package isn't specific to one language. It applies to all supported languages.

One CU package includes all available updates for all SQL Server 2022 components (features). However, the cumulative update package updates only those components that are currently installed on the SQL Server instance that you select to be serviced. If a SQL Server feature (for example, Analysis Services) is added to the instance after this CU is applied, you must reapply this CU to update the new feature to this CU.

If other issues occur, or if any troubleshooting is required, you might have to create a service request. The usual support costs will apply to additional support questions and to issues that don't qualify for this specific cumulative update package. For a complete list of Microsoft Customer Service and Support telephone numbers, or to create a separate service request, go to the Microsoft support website.

1. In Control Panel, open the Programs and Features item, and then select View installed updates.
2. Locate the entry that corresponds to this cumulative update package under SQL Server 2022.
3. Press and hold (or right-click) the entry, and then select Uninstall.

To uninstall this CU on Linux, you must roll back the package to the previous version. For more information about how to roll back the installation, see Rollback SQL Server.
