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 nervous 
about switching to another platform. I have 
heard excellent things about blogengine.net. Is there 
a way I can import all my wordpress content into it?
Any kind of help would be really appreciated!
