Import from Sermon Speaker for Joomla 2.5

I am in the process of rebuilding our website and migrating to Sermon Speaker 5 on joomla 3 but I wasn't able to simply upgrade my Joomla 2.5 to 3.0 so it's a fresh install, is there an easy way to import all my database files to bring all the old data.

Maybe grab all the tables and import them in MySQL then install the new version of SS.

You need to install exactly the same version of SermonSpeaker in Joomla 3.x as you have installed in your Joomla 2.5.
After that you copy all database tables starting with #__sermon to the new database, overwriting the existing tables. You can do that with tools like phpMyAdmin.
After that, you can upgrade to the latest version of SermonSpeaker.

You will have to recreate and reassign the categories for the sermons, speakers and series as you can't simply copy them over. You can reassign the categories easy using the batch functions in the respective managers.
As long as the assigned categories are invalid, the entries will show in the backend, but not in the frontend.

I too am trying to achieve this migration.

I have followed the instructions in this thread, but am getting the following error when importing my sql file (containing the old databases tables - renamed to the new prefix):

#1062 - Duplicate entry 'level' for key 'PRIMARY'

I have definitely dropped the tables _scriptures, _series, _sermons, _sermon_tags, _speakers and _tags, so I don't know where it is getting the duplicate from?

You only need to import the SermonSpeaker tables. It reads like you're importing all tables from the old Joomla installation.

No, I'm only importing the 6 said sermon speaker tables.

That's strange then. The primary keys of the SermonSpeaker tables all only contain integers. So there is no way a "level" value can or should end up there. Even if you haven't dropped the tables, you shouldn't get such a message.
Your exported SQL files maybe are corrupt or something?
