moving individual blogs from subdomain site to a subdirectory site

I have little hops of restoring blogpeoria.com.

So, i want to move the handful of highly successful and still active member blogs to my new citizen journalism site, tellpeoria.com.

BlogPeoria was set up using subdomains.

TellPeoria uses subdirectories.

I am looking for as much advice as possible.

Right now, I cannot access any admin page on BlogPeoria.com, so the export feature is unavailable

Where do i go in the database of blogpeoria to see what number table any individual blog uses/

Can I just download that blog’s tables into its own file, and simply upload them to the tellpeoria.com data base?

Like I said, much advice is needed and any given is much appropriated.
