upgrade

The following post originally appeared on the GoingOn.com blog.

After more than a year of continuous investment in GoingOn’s Drupal 6 platform, the idea of upgrading to Drupal 7 is incredibly daunting. We have custom modules from form behaviors down to the access layer, we have features encapsulating hundreds of exported components, and an aggressive feature release schedule that does not set aside 6 months for a complete rewrite of the codebase just for a new version of Drupal. What to do?

We’ve been playing around with the idea of iterating our Drupal 6 platform toward Drupal 7. By pulling markup, design patterns, APIs, and architecture in Drupal 7 down into platform incrementally, we hope to shorten the final leap that will come when upgrading the entire system.
