I'm looking to upgrade my drupal site from 5 to 6. The problem is, I can't have the site down for very long and I don't want to risk a straight upgrade (when I built my site originally I hacked together a lot of bad code and I know there'll be problems). What I want to do is basically install drupal 6 on the server where I can work on it, then when everything is in good shape, move it in place of the drupal 5 site. Can this be done and is this the best way to go about it?

If the Drupal 5 site is left live, it will contintue to collect data and will be out of sync with whatever you do on the upgraded site.
Even if you were to take a snapshot of the D5 site's DB just before you are ready to move, that database will have to be upgraded again.
