We are currently running Jira Software 8.13.15 on or internal test instance. We want to upgrade that to 8.13.20. The original instance was installed using the linux binary installer. The upgrade notes say:
Avoid using this upgrade method if you initially installed Jira using the binary installer (.exe on Windows or .bin on Linux). Upgrading binary installations manually is not supported and is known to cause problems on startup.
But there is no link that shows how to do an upgrade then or suggest an upgrade method. Any thoughts?
