I have an old Jira Server instance whose contents I would like to migrate to Jira Cloud. Jira Cloud will only accept an import from 7.6.0 or later and my Jira Server is on 4.3.3. To update my Jira Server, I would have to renew its maintenance license but doing so requires me to pay for the license for all of the past 9 years, which is a staggeringly steep fee just to get an export in a more recent version.
Are there alternative options? The backup is just XML data so converting it to whatever the current data structure is should be simple, relatively speaking.
