An important SEO question: how get these custom url's?

I bought Easyblog and imported a lot of my old blogs into Easyblog. My old blogs have this kind of url's: http://www.domain.com/title-of-the-blog

How can I arrange these kind of url's? In the SEO settings a custom url always start with http://www.domain.com/menu/title-of-blog

It is very important to fix this for my old links.

Thanks.
