Changing the Stack

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

FlowFuse allows you to change the stack an instance 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 instance is using, the platform will notify you that there is a new version available.

To change an instance's stack:

1. Go to the instance's page and select the Settings tab.
2. Click the Change Instance Stack button.
3. You will be prompted to select the new stack.
4. Click Change Stack

Your instance will now be restarted on the new stack.

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