REST API - fetch all backlog items

Question

I'm looking for the API, or combo of them, which will help me fetch an entire backlog from hosted jira so that we can move those issue to our local instance.  I can't do the standard XML import because that would over-write what already exists, so I have to use the APIs.

Next. I'm getting a licensing error on the import from on-demand. "Invalid License Key Specified"

Next issue.  Instead of testing between my prod and my test instance, I tried an import from hosted to my test instance (our company has about 300 developers, and the different teams are paying for their own hosted instances out of their own budgets - I need to bring them ALL to our local instance).  My test instance was just upgraded to 6.2.3#6260, but the hosted is 6.2.3#6318.  Of course, the project import failed.

From the documentation, it looks as if I need to just import the hosted instance data to the test on-prem instance.  Will that work, even if I'm on different releases?

OK, I did the xml export, but when I import by project, I'm erroring out on a bunch of custom fields.  Looks like I'll have to create all of those custom fields in my local instance to match those in the hosted instance.
