My coder is trying to convince me to move to .net from PHP.

I have always disliked the idea because of the costs. But he's 
tryiong none the less. I've been using Movable-type on a variety of 
websites for about a year and am worried about switching to another platform.
I have heard great things about blogengine.net. Is there a way I can transfer all 
my wordpress content into it? Any kind of help would be really appreciated!
