Changing Themes

Hi Guys I’d appreciate some advice.

I’m in the process of changing from a standard theme to a magazine theme: Prosense Blue to Brandford-Magazine. Now I have quite a few posts in my Prosense Blue Theme but it’s a big change over to a magazine style theme; any advice, any tutorials that I might usefully read up on.

Is it a difficult task to change from a standard theme to a magazine style theme.

Don’t be afraid to add any addional information.
