My coder is trying to persuade me to move to .net from PHP.

I have always disliked the idea because of the expenses.
But he's tryiong none the less. I've been using Movable-type on various 
websites for about a year and am anxious 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!
