Import blogs from Idoblog into CB PB possible?

The migration from Joomla 1.5 to 2.5 killed Idoblog so I had to install another one (Easyblog). Now I found that CB Profile Book can do the same but the import of the old blog entries does not work. Idoblog saved all entries in its own categorie "blogs" while the sections got the usernames. So far so good, importing should be easy. Unfortunately I get messages like "no item selected" even when I select items. Is there any documentation, howto or whatever?

There's no such import feature. You'd need to convert the database entries to entries into the profilebook database.
