Someday you'll likely want to do the same. But this is a major upgrade, not a trivial "Drupal 6.19 to Drupal 6.20" kind of affair. "Yeah, one of these days I need to get around to that", you say... while your poor D6 sites fidget anxiously... like nervous freshmen huddling outside the gym locker room... fearing the gauntlet of cackling seniors daring them to walk on in....
Oops, sorry; serious flashback. Anyway, a major upgrade is a can't-avoid-it-forever exercise, so let's charge in. I ran into problems during my experience (gee, there's a surprise : / ), but I managed to fix them as outlined below. If you've got a Drupal 7 installation running and are ready to uplift an old site or two, read my tale and let me know if it's of any help!

Following up on my review of the book Drupal 7 First Look, here's a closer look at the creation of my first Drupal 7 site: a generic "sandbox" site to be used as the base for future sites. While every Drupal site you or I create will call for its own unique setup, there are parts of a Drupal configuration that I'll likely want to replicate on any new site, such as installation of key modules, or creation of useful roles and vocabularies that I always end up using. I'd prefer to do those things just once, rather than from scratch every time; hence the sandbox site.
Summary: Good developer-oriented overview of what's new in Drupal 7.
Putting the book to work
Drupal 7 First Look (hereafter First Look) was released by Packt Publishing in November 2010, several weeks before the official release of Drupal 7 (D7) itself. "Learn the new features of Drupal 7, how they work and how they will impact you", runs the book's subtitle – a goal of interest to site builders awaiting D7's release at the time, and site builders now who've yet to approach D7 months after its release.
One common Drupal beginner question is "What kind of site can I make with Drupal?" – followed quickly by "How do I make that kind of site?". It's not hard to find answers. In addition to great Drupal.org resources like the Site recipes page, the Web abounds with lists of inspirations and how-to recipes for your next Drupal creation. Read more about Drupal site recipes
