My programmer 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 good things about blogengine.net.
Is there a way I can transfer all my wordpress posts into it? Any help would be greatly appreciated!
