we have an apache tomcat installed with jira core. Why apache tomcat is used?
Jira is a Java based program. Since Jira needs an application to host its website, it makes sense that Atlassian uses Tomcat since this too an a Java based webserver.
You can't do this in a single upgrade. You are going to need to upgrade to at least one intermediate version first (a 7.0.x version).
I would recommend that you use the Upgrading Jira with a fallback method. This method might take some more time to complete, but it offers the best means to make sure your data is properly upgraded and users suffer the least amount of downtime possible.
