I am trying to find out how long version 5 will be supported.
Depends on the mid-level version is (5.1 will be dropped this week, 5.7 around Christmas, etc, all of 5 dropped by next Christmas)
See https://confluence.atlassian.com/support/atlassian-support-end-of-life-policy-201851003.html - it's the policy and Atlassian put dates on to save us some time.
