I m admin on site which is powered by Seditio (ex. LDU) and day by day I miss Joomla… not because I m Joomla user for a year, it`s because the lack of support for seditio plugins, themes, mods and other things that Joomla has… Seditio is pretty hard solution for a sites that have more than 2000 members and a lots of pages… We currently have around 2650 members and since i got the administration rights i m trying to improve that site..
Can anyone tell me how to successfully migrate Seditio database to Joomla?
Is there any tool to do this or maybe some tutorial to help me understand the whole proccess?

Any help will be apprecited.

I didn't find the right solution from the Internet.
