Upgrading from version 5.1.7 to 6.3

Question

Currently my company is running JIRA version 5.1.7.  We are having issue with versions of Java that are higher then 1.7.45 when attaching screenshots.  From what I am able to tell we this is because of the validity of the JIRA cert which was only good until 01/16/2013.  It would appear that we can solve our problem by upgrading to a newer version of JIRA. I am not 100% of what it would take to make the jump from 5.1.7 to 6.3 and how complicated it would be to do so.  The other part of this is that JIRA is a highly critical part or my teams daily job.

Any help would be appreciated.

It is a straight upgrade but you need to look at the plugins and customizations you have to know the exact complexity.

And of course, test it!
