drupal 5

Here is a great screencast video that covers the steps necessary to upgrade a Drupal 5.x installation to Drupal 6.x. Make sure you also read these basic instructions on upgrading from Drupal 5.x, and the video should give you a more comfortable understanding of the steps involved.

Backup a lot and happy upgrading.

This is an extract from the Drupal 6 release announcement. If you are planning to upgrade from Drupal 5.x make sure you read this post carefully:

• Ensure that you have Drupal 6 versions of all of your contributed modules and themes, and that you have reviewed and updated your site's custom code (if any).
• When upgrading, always save backups of your original files and database.
