- Cumulative updates are now available at the Microsoft Download Center.
- Only the most recent cumulative update that was released for SQL Server SP3 is available at the Download Center.
- All fixes that are described in this article will be included in all future SP3 cumulative updates.
If the download page does not appear, contact Microsoft Customer Service and Support to obtain the cumulative update package.
Note After future CUs are released for SQL Server 2012 Service Pack 3, this CU can be downloaded from the Microsoft Windows Update Catalog. However, we recommend that you install the latest CU that's available.
- Each new Cumulative Update (CU) contains all the fixes that were included with the previous CU for the installed version/Service Pack of SQL Server.
- Microsoft recommends ongoing, proactive installation of CUs as they become available:
- SQL Server CUs are certified to the same levels as Service Packs, and should be installed at the same level of confidence.
- 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.
- Just as for SQL Server service packs, we recommend that you test CUs before you deploy them to production environments.
- We recommend that you upgrade your SQL Server installation to the latest SQL Server 2012 service pack .

- Upgrade and update of availability group servers that use minimal downtime and data loss.
Note If you enabled AlwaysOn with SSISDB catalog, see the information about SSIS with AlwaysOn for more information about how to apply a CU or SP in these environments.
