We're interested in purchasing a license for Jira Enterprise, but we have to purchase a corresponding license for Greenhopper.
The Greenhopper documentation makes no reference to the Enterprice license at all:
http://www.atlassian.com/licensing/greenhopper
The information about Greenhopper enterprise license is available only on the Jira Enterprise page.
The cost to upgrade to the enterprise Greenhopper license is $2000
However, I think I'd prefer if there was some value add to this Enterprise offering.
Specifically:
* Access to Atlassian University training courses for Greenhopper
* 24x7 support phone and online
* Some form of certification
