How do I get all project data from a JIRA 4.3.2 server to a different server with JIRA Software?

Question

We have an old JIRA 4.3.2#616-r148546 server, and are moving to the newer JIRA Software / 7.x. How can I get all of the data from a (one or more) project(s) on the old server into one or more projects on the new server? We don't want to lose comments, attached files, etc.

I assume this is a "merge?"  The JIRA 7 server already has active data in it?

Export the 4.3 stuff to XML and use that to create a temporary development 4.3 server.  Delete as much as you can, removing any project you know you don't want to carry across.  Upgrade that server to JIRA 7.x.  Export the xml from there, then use "project import" to pull the issues in (bearing in mind you will have had to manually create the target projects with the right config)

If that sounds hard, yes, I'm afraid it is.  If you're willing to compromise on the "everything", you have some other options.  Or if the JIRA 7 is empty, then it's a lot easier - upgrade a copy of the 4.3 and make the upgraded one your production system afterwards.
