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 several websites for about a year and am concerned about switching to another 
platform. I have heard excellent 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!
