JIRA - I am looking for archiving options, please

Hello. I am looking for options to archive in JIRA. We have to archive certain issues which contain development info for 5 to 25 years in a format (pdf, html…).

I would prefer a plugin (as an exporter) or a program that picks issues and archives them.

First of all we got the Atlassian documentation that shows you what the program itself can do: Archiving a project | Administering Jira applications Data Center and Server 7.1 | Atlassian Documentation

And of course our plugin or add-on Project Archiver for JIRA: Atlassian Marketplace
