Hi
There are a couple of different guides out there on how to upgrade. The issue I have s that I'm not sure if I have to use the JIRA Core or the JIRA Software installer to do the upgrade:
When I look at my licenses I seem to have the both but only one has a license attached. Is that an issue:

And when I try to download the installer it says I have to download both but it only downloads the core!
There is also the issue this guide tells me I can put JIRA in an upgrade mode. But this option does not exist for me (https://confluence.atlassian.com/adminjiraserver073/upgrading-jira-applications-861253088.html).
I run JIRA on 64bit Linux server. Can you tell me exactly which installer I have to use and how I should run the update? I found those 2:
atlassian-jira-core-7.10.2-x64.bin
atlassian-jira-software-7.10.2-x64.bin
