# Upgrade Tableau Server Overview

The topics in this section help you upgrade an existing installation of Tableau Server on Linux. They describe the recommended steps of planning and testing before actually performing the upgrade. There's information about best practices, and when you're ready to actually perform your upgrade, steps for upgrading a single node server and a multi-node installation. Where possible, we call out possible pitfalls and help you to avoid these.

**Note:** Use [Tableau Release Navigator](https://public.tableau.com/shared/YZ62TW35F?:display_count=n&:origin=viz_share_link) to search for features in Tableau Desktop, Server and Prep, or to see a full list of features when comparing your current version of Tableau to a later one.

### Upgrading computer operating systems

**Important:** Any major version operating system or Linux system kernel upgrade (for example: RHEL 7.x to RHEL 8.x) must be done using Blue/Green guidelines. **Do not do a major version upgrade directly on a machine already running Tableau Server.** Even if you follow the steps below, Tableau Server will be in an unstable state if it starts at all.  
  
**Doing a major OS version upgrade directly on a machine that is running Tableau Server will render your Tableau Server installation unsupported.**  
  
For details on Blue/Green upgrades, see [Using a Blue/Green approach for upgrading Tableau Server](https://help.tableau.com/current/server-linux/en-gb/server-upgrade-blue-green.htm).

If you are upgrading the operating system of the Tableau Server computer, or nodes in a cluster, be sure to review and follow the best practices for upgrades. **Major upgrades (for example:** **RHEL 7.x to RHEL 8.x****) must be done using Blue/Green guidelines.** For details, see [Best Practices for Updating Your Tableau Server Computer](https://help.tableau.com/current/server-linux/en-gb/upgrade_best_practices_server.htm) and [Using a Blue/Green approach for upgrading Tableau Server](https://help.tableau.com/current/server-linux/en-gb/server-upgrade-blue-green.htm).

## Choose your upgrade path

### Blue/Green upgrades

Blue/green upgrades are a special type of upgrade approach that provides minimal downtime, but requires a knowledgeable IT team and resources to implement. These are not appropriate for every organisation, but they can be the right upgrade solution for those with the appropriate technical knowledge and staff. For more information, see [Using a Blue/Green approach for upgrading Tableau Server](https://help.tableau.com/current/server-linux/en-gb/server-upgrade-blue-green.htm).
