First hit on any search engine is the standard upgrade documentation you need to start with. https://confluence.atlassian.com/adminjiraserver/upgrading-jira-applications-938846936.html
Here is your link.... https://confluence.atlassian.com/adminjiraserver073/installing-jira-applications-on-linux-861253030.html
I advice you to read the documentation in each upgrade seperately, e.g v7.3 to v7.4 , v7.4 to v7.5 and so on! So you are full informed about the changes which made i each version
Then you can determine what is the best way for you to make the upgrade!
Best regards
