Yes, this will pose no problem. We do it commonly. You can simply install your v9.0 server, as Szymon has suggested, on another port to effect your testing. Be sure you've set up a 9.0-compatible cluster of course; you can't share data.

We need to have, for migration, either an instance of our actual PG 8.4.4 and a new one of PG 9.0 for testing.
Where can we found a paper for helping us?

I think there is no paper on that, that's just too simple. Install another database, run it on another port (that needs changing one value in the postgresql.conf).
