Moving emails from one thunderbird to the next

I have located the profile files, but now I am at a loss as to how to do this.

On one computer, I have some emails. On another I have all my old emails. I want to move my old emails over to the new computer. But the directions I have seem a bit unclear on how I can combine the emails from both PCs without overwriting anything that might be important.

I'm using Vista. I just want to combine two email profiles onto one thunderbird.
