How does that help?  The JIRA import feature seems to operate on the
live Bugzilla instance, or at least the live database.  I can see that
doing a migration over the internet would be slow and possible prone
to time out errors.  I suspect there are a variety of approaches
possible:

Would it be unnecessarily complex to do a Bugzilla dump, import to a
temporary Apache Bugzilla instance, then import into to the real
Apache OOo JIRA instance?  Advantages are if we need to redo the JIRA
conversion due to problems, we can iterate on that step much faster.
It is also an opportunity to ensure we're starting (hopefully) from
the latest stable Bugzilla rev, which may migrate easier.

Good point on the patches.
