Prior to the recent changes to JIRA, we were completing initial development/POC of JIRA Service Desk. After review, the decision was made to purchase it in November (after JIRA Core/Software release), so we now own a license for JIRA Service Desk 3.
Sadly, we are not yet ready to update our production environment from JIRA 6.4.7 to JIRA Software.
Is it possible to install JIRA Service Desk 3 (so that we can utilize our license) on a pre-7.0 version of JIRA?
