Hi,
I want to upgrade old JIRA instance 6.0.1 to 6.4.
Please let me know what is the fastest way to do this because my current approach would be to take every little release 6.0.2, 6.0.3, ...,6.4.13, 6.4.14 and install them one by one.
Could I skip some versions and go ahead quicker ?
Thank you for any help.
Regards,
Rafal
