My coder is trying to persuade 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 
very good things about blogengine.net. Is there a way 
I can transfer all my wordpress content into 
it? Any help would be really appreciated!
