Migrating WordPress databases

Since I’m migrating content from one wordpress blog to another for the purposes of playing with the wordpress themes (trying to create a theme that I like), I learned a bit about the database along the way.  Like the fact that there are values within the database that point to the database table prefix used when you first set up the database.  If you change that prefix (to say host two copies of the same blog in two locations so that you can do dev work on the second version), then suddenly you’re “locked out.”

I found a nice article that helped me understand what was going on.

Thank you, kudos are due.
