I decided to take a couple of my personal blog and refine them to be single topic focused.  I researched and found out the feature to export and import WordPress item was built-in.   In the Tools option, there is an Import and Export command.  I ran the Export command and use a Category to select all the posts I wanted to move.  It created a XML file which I imported into the other blog.  It was very easy and even handled the imaged.
