Upgrading Image Module from Drupal 5 to Drupal 6

There have been some issues surrounding the upgrade path for the image module from Drupal 5 to Drupal 6.

In order to successfully upgrade, you need to:

Prepare Your Drupal 5 Install

1. backup your database
2. upgrade to the latest image 5.x.-1.x module
3. then upgrade to the latest image 5.x-2.x module

Upgrade to Drupal 6

1. backup your database
2. follow the Drupal 5 to Drupal 6 upgrade instructions
3. upload and install the latest image 6.x-1.x version of the image module (or other appropriate release)
4. run update.php
5. that should do it

Why

The key here is a code structure change in the image module in version 2.x that is important to update prior to your upgrade to Drupal 6.

Note

At the moment, the image module is in alpha and you must always be careful when dealing with alpha code. The current alpha is fairly stable but you should always, always, test the module prior to using it on a live production site. If you have any problems, please document any errors you receive and review the open issues list for the image module. If you do not find any immediate solution, post a support request with as much description as possible.
