We are currently running JIRA 5.2 with the WAR File. Now I have to upgrade it to the newest Jira-Version and migrate to a new Server, running CentOS 6.5. On the new Server I'd like to go with the .bin-Installer, which should make it more easy for future upgrades.
Is there a "best way" to change from war to the .bin? How would you guys do it? I couldn't find anything about it in the documentation. 
Regards
Marco
