Here is my problem: I have been blogging for about six years now at [Blogsome.com][1]. I've had no problems with it whatsoever, until a few days ago, when they suddenly announced that they were going to close down on a very short notice. So at the moment I'm looking for a new blog. 

At the moment I'm thinking of going for a cheap hosted server. My problem is that I want to import all my old posts in the latest version of Wordpress. This is problematic because:

 - The SQL dump I got out of their backup page is really big (about   
   30MB). Will this safely import into a new wordpress site?
 - Blogsome never updated their wordpress version, so it has been stuck
   at Wordpress Version 1.5.1 for more than half a decade now. How can
   this SQL dump be safely imported into a new version of Wordpress?
   It's unfortunately the only way I managed to export my blog's
   database. Blogsome does offer a WRX-file backup option, but that one
   unfortunately is broken.

So what would be the smartest way to handle this?
