At present, Jira6.4 is running normally and stably, but development needs a function, which is only available for Jira8.0+. Can I upgrade from 6.4 to 8.3.1?Thank you very much!
Hi,
first, try an upgrade on a test/staging environment before doing it on production.
second, do an upgrade from 6.4 to latest 7.x first, and after this, from 7.x. to 8.3 or later.
