Where can I find information on which of the different releases are compatible with one another? For instance, is JIRA 5.0.2 compatible with Crowd 2.0.7? Do I have to upgrade all of my tools at the same time (i.e., Bamboo, Confluence, Fisheye, Crowd, Clover, Greenhopper). Right now I can't seem to get my 5.0.2 to populate and allow access to an import from 4.1.2 JIRA. Is this because of release compatibilty issues or not? Now I have management looking for a schedule for upgrades for each of the tools and I can't honestly answer them that they don't require an upgrade at the same time or not. I can't find any information on this anywhere.
