My developer 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 various websites for about a year and am worried about switching 
to another platform. I have heard very good things about blogengine.net.

Is there a way I can transfer all my wordpress posts into it?
Any help would be greatly appreciated!
