I am researching the upgrade process from JIRA 4.2.4 to 6.3
Our team uses FishEye/Crucible (2.5.1), Crowd, and Confluence and I can't seem to find a version compatibility chart on the Atlassian site.
I'd like to find out what mandatory upgrades I will need to do and whether any of those are bundled with the JIRA license or whether they are a separate purchase.
Any information would be appreciated. Thanks!
