The number of sites running Drupal 7 has been steadily climbing over the past few months, and is now north of 140K sites. At the same time, the number of Drupal 6 sites has started to flat-line.
So if you haven't started yet, now's a great time to begin thinking about and planning your site's upgrade path to Drupal 7.
To assist with this task, there's an amazing, little-known module out there by sun called Upgrade Status, which is an essential tool in the site upgrade planning process. It will inspect the modules installed on your site give you a custom-tailored report about each of their porting status to the next version of Drupal. It also provides other upgrade helpers, such as a block with links that walk you step-by-step through the process of a major upgrade.
Obviously, though, the biggest barrier to doing D6 -> D7 site upgrades (apart from time, of course :)) is the porting status of contrib. So using the magic of Upgrade Status module's data I've set up a site at http://drupalcontribstatus.com/ to track the status of the top 60 contributed projects (the top 50 + 10 that were moved into core):
The intent of this site is to act as a dashboard for folks who want to help the module porting process happen faster. There are helpful links track the issues that block a D7 release (a convention established in a previous post), issues that need review, instructions for how to take over abandoned projects, and so on.
We're currently at 32 of 60 projects ported (though obviously, most of the betas/alphas of these modules are pretty solid or we wouldn't have 100K+ D7 sites...). Can we hit all 60 by the end of the year? :) Let's try! If every DrupalCamp between now and then focused on a few of these remaining modules, I bet we could do it!
PS: Feel free to use the Contrib Status module to set up your own site to publicly track and create momentum around specific modules you care about. But WARNING: The code was largely written between the hours of Stupid O'Clock and Why Are You Still Up Dummy, so I take no responsibility for it whatsoever. :P~ If you have ideas on how to make it better, please leave feedback in the issue queue!
