Hi, we planning on upgrading our Jira server from Server 2012 to Server 2016 and I'd like to upgrade our Jira software to a version supported by Server 2016 before the OS upgrade. I'm thinking going with the earliest stable version that is compatible with 2016 would be best. I've tried to review the documentation on upgrades but am getting very confused. Can you please provide the recommended upgrade process we should follow to have a successful upgrade? Note, we have a very small Jira environment that is not mission critical so we can tolerate downtime during the upgrade. The Jira DB is running on SQL 2012 running on a Server 2016 server.
Thanks,
Frank
