Dear friends!
Yes, the Kabissa team has been drinking the koolaid lately, and we're feverishly working to migrate our Joomla site to Drupal.
In the coming weeks we will be moving our content over and moving our member database into civicrm and a "web 2.0" style member directory. As some may recall, we initially planned to do this with Joomla/civicrm (our specs are still up on the civicrm.org site) but have now decided to shift to Drupal/civicrm.
I've been looking at the "Migrating from Joomla/Mambo" guidebook page here: http://drupal.org/node/80195
It helps, but does not provide a script/recipe for actually migrating the site. I outlined what I'm trying to migrate and the steps that seem to be required in a comment to that page, here: http://drupal.org/node/80195#comment-232717
I know this will not be a turnkey affair, but still I feel that it could be made easier. Perhaps others on this list have had better luck (or know somebody who has). I'd be massively grateful for any advice from others that have been through this before us, or a volunteer to work with us on the actual migration and to expand on the guidebook page. I suspect that folks will be migrating their community websites in droves as they realize what Drupal 5.1 can do, and we need to be more welcoming to them.
Cheers,
Tobias
ps - I had a dig around the drupal.org forums today, and noticed the site was excruciatingly slow to load (20-30 seconds a page at times, esp in the forum) and got "throttling" messages when trying to contact people. Submitted a ticket to the webmasters but I am still curious to hear what's going on with the www.drupal.org site, esp as we are migrating to this platform.
