I have finally managed to get the licence renewed under Atlassians Opensource agreement.  It has been associated with the email address admin[at]openvpms[dot]org which will essentially function as a Openvpms Team account with atlassian.

I plan to look at upgrading the Jira instance to the latest production ready version of Jira in the near future.  The version we run was released in 2011, the update should bring in a nice raft of features that improve workflow when working with Jira.

To that end I am pasting in the Upgrade Issues for each Version we are skipping.  For those interested please review and comment if there are any deal breakers.
