#  Changing the Stack

Project Stacks define various aspects of how the project is run - including the version of Node-RED being used.

FlowForge allows you to change the stack a project is using - providing a way to upgrade Node-RED.

Note: Stacks are created by Administrators and made available to the teams and users of the platform.

When an Administrator creates a new version of a Stack your project is using, the platform will notify you that there is a new version available.

To change a project's stack:

1. Go to the project's page and select Settings in the sidebar.
2. Select the Danger section in the side menu
3. Click the Change Project Stack button
4. You will be prompted to select the new stack for the project.
5. Click Change Stack

Your project will now be restart on the new stack.

Note: Changing the stack causes the project to be stopped and restarted. This will require a short downtime of the project flows.
