We care currently running JIRA 6.4.3 server with an up-to-date maintenance contract, but we let our Agile license expire in January 2016. We are now planning to perform an upgrade to JIRA Software 7.x and want to be able to use the built-in agile features in that version. Does it matter if our Agile license for 6.x expired as long as our JIRA support license is current?
