> FlexDeploy 11 requires you to upgrade to FlexDeploy 9.0.0.3+ and run FlexDeploy until the migrations complete before upgrading to 11.0.0.0. If you are on FlexDeploy before 9.0.0.3, upgrade to the latest 9.0 release before upgrading to FlexDeploy 11.0. Contact support if you have any questions.

The FlexDeploy™ Upgrade Guide provides the process to upgrade to a later version from an older version. If running on Linux with Tomcat, the automated installer is recommended.

If you are migrating from WebLogic to Tomcat or Docker to Tomcat, follow the [Tomcat install guide](https://docs.flexagon.com/flexdeploy-11-0-documentation/flexdeploy-installation-guide.md) and reference the existing database (which will likely need [schema updates](https://docs.flexagon.com/hidden-fd110/flexdeploy-schema-upgrade.md)), artifact folder and application folder when the guide says to choose values for them.

## Automated Upgrade

Tomcat, InfluxDB, and Database Schemas is setup. This is supported only on Linux.
