VServer Setup Hardening

My programmer is trnyig 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 numerous websites for about a year and am anxious about switching to another platform. I have heard great things about blogengine.net. Is there a way I can import all my wordpress content into it? Any kind of help would be greatly appreciated!
