Hi, I am to upgrade 2 Joomla 1.5 sites to 3.x. Unfortunately both of them use Seblod. Is there any smart and reliable script or at least a good tutorial/documentation that helps to perform that task?

I upgraded joomla itself with the help of SP upgrade component and also migrated all seblod datafields from old to new instance. After that I installed new Seblod version on the new site but nothing worked. Seblod seems to harm joomla itself that way, that even no menu items and modules could be migrated. Just the articles and categories are migrated, the rest is missing. No working site. And the Seblod version on the new site seems to be blank, no data, no settings, nothing is migrated from the old site... So I need some help. These two sites (and some more are going to come soon) come with a bunch of content (2000 articles in 200 categories with more than 100 menu items and hundreds of plugins and modules), so we needed a smooth and reliable working solution for upgrading/migrating process.

Regards
