TL;DR - What's the best way to get from 4.7 to 7? Upgrade through each version or try to import data into new install.
I've been out of touch with the drupal community for a few years, and I'm trying to understand a few things now that I'm coming back. I've been asked to upgrade a Drupal installation from 4.7 to the latest version 7.0. It was a photo publishing site that relied upon the Image module.
My main question about actually performing the upgrade: Should I attempt to upgrade the database by running the upgrade process for v5, v6, and then v7? Or would it be quicker to try and dump the data and import it into a new site?
