Upgrading Joomla 1.5

I currently have a site that has been using easyblogger for a very long time, since joomla 1.5. I need to upgrade the site to 3.0. Because there does not seem to be a way to really upgrade from Joomla 1.5 to 3.0 I am installing a new joomla 3 and then installing all the updated components I currently use, and either redoing everything or importing tables from the database. I read on these forums somewhere that I could install easyblog on the joomla 3 site, then import my joomla 1.5 database and everything will be fine as long as I change my jos_ table names before importing, which I did. But then when I add easyblog to the menu I get this page:

This tells me that just importing your old easyblog database tables to a joomla 3 site isn't the correct process. I really need to upgrade the site and Easyblog is the CORE of everything else on the site. Thanks for any guidance you can provide, I have been at this every day for a week, hours a day. Installing and uninstalling.
