After putting it off for almost 2 years, I’ve finally decided to make the upgrade from Drupal 4.7 to 5.1.  My hand is being forced a bit by the ongoing issues we’ve been having, but I really am looking forward to all the new features that Drupal 5.x provides.

Over the last few evenings I’ve been setting up the test-site and tonight I actually went thru the upgrade process on the test-database.  To my surprise it went very smooth, and I only encountered a few minor issues.. Critical modules, like Taxonomy Access Control, which controls the permissions on our premium content had no issues whatsoever.  As a matter of fact, all the testing went so well that I’m now planning to upgrade the production site on Friday.

I’ve been testing for the last 7 hours so i’m going to bed – after the production upgrade I will post all the step-by-step instructions for those interested in doing a similar upgrade.
