My organization currently uses JIRA, Confluence, and Crowd. We are considering adding Bitbucket as well, but we have questions about users. Currently we have a license for 2000 users with Crowd, JIRA, and Confluence, but we don't need anywhere near that for Bitbucket. In order to integrate Bitbucket with these other products does it require 2000 users as well, or can we get a license for 250 users instead? That's a difference of roughly $40,000.
