My programmer is trying to convince 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 numerous websites for
about a year and am concerned about switching to
another platform. I have heard good 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!
