How do you disassociate a workflow from a project?

[jroberts@zerochaos.com]

I have copied and modified a workflow but cannot make it active. JIRA tells me that I must disassociate the active workflow from the project before I can make the copy active. I can not find a way of doing this.

You'll need to make a new workflow scheme (you can just copy your existing one), then associate the new workflow with the new scheme, then associate the new scheme with the project.
