Yes, Jackrabbit should continue to work without problems over such an
upgrade. Though take a look at the backwards compatibility section in
the Jackrabbit 2.0 release notes [1].

Anyway, as a standard precaution and especially since you're upgrading
over quite a range of versions, getting a full backup before the
upgrade is of course recommended.

There should be no absolute need for extra steps, but for example
reindexing will allow Jackrabbit to update the index format to a more
recent and efficient one.

There are also a lot of other performance and scalability improvements
that can only be enabled by switching to a newer repository
configuration. For example in your case, since you're dealing with
lots of binaries, using the data store would be a good idea. Also a
pooled persistence manager should give you some boost in concurrent
read access performance. However, such improvements would require a
full content migration as described in [2].
