Review the [release notes](https://documentation.decisions.com/v99/docs) for the desired version to identify potential breaking changes. Breaking changes can also be viewed by using the [Upgrade Validator Accelerator](https://documentation.decisions.com/projects/docs/upgrade-validator). It is recommended to use the scanner before upgrading. The scanner only shows breaking changes for v9.0 and above.Back Up Before Proceeding Before continuing with any update, the following should be backed up to avoid potential errors during the process: - [**Database**](https://documentation.decisions.com/version-10/docs/backup-of-decisions-database-and-file-system) and **F****ile S****ystem** - make a note of the DB Server and DB Name - [**Settings.xml**](https://documentation.decisions.com/version-10/docs/system-settings-overview-settings-xml) - found at  C:\Program Files\Decisions\Decisions Server - [**Keys.dat**](https://documentation.decisions.com/version-10/docs/storing-encryption-keys) - found at C:\Program Files\Decisions\FileStorage\Primary\Settings - **FileStorage** **Folder** - found at C:\Program Files\Decisions\ - [FileStorage Settings](https://documentation.decisions.com/v9/docs/environment-variables#changing-the-default-file-storage-location) (for Containerized Environments) - /opt/decisions/data --- ## Overview Throughout a major version release (for example, v9), additional minor releases (such as v10.2 or v10.1.3) are periodically released to address new features, bug fixes, and security and stability issues within the platform. In such instances, Decisions Installations of a matching major version can be updated using [DecisionsServerInstaller.exe](https://releases.decisions.com/Releases/). **Upgrading a Clustered Environment:** - **IIS-hosted:** Turn OFF the Decisions Services on all the Nodes. To do so, run `iisreset/stop` from the Command Prompt/PowerShell as Administrator. - **Self-hosted:** Turn OFF the Decisions Services on all the Nodes. To do so, Stop the Decisions Services from the Windows Services. - For more information on upgrading a containerized environment, please see: [Decisions Container](https://documentation.decisions.com/docs/decisions-container-1). - Follow the given steps and upgrade the nodes one after another. Ensure you upgrade the second node only after the first node's upgrade is completed and the service is running. ### Prerequisites - Pre-existing **major version** installation. - When running a Self-Hosted environment, IIS (**Internet Information Systems**) must be stopped via the **Stop** action; this prevents potential **Port** conflicts in the update process. ![](https://cdn.document360.io/6ef8bcc1-6489-4486-9ad1-83acff7e5df0/Images/Documentation/2022-06-09_15h28_18.png) --- ## Example 1.
