 * Can I use the backed up databases for the tables wp-posts and wp-comments from
   2.2 and bring it in to 2.3.1? If possible, anything I should change / think about
   before doing?
 * Unfortunately my blog broke down, big time, got blank pages in all the crucial
   places, which made it impossible to upgrade. Also, I couldn’t export my posts
   and comments, which means that my last hope is being able to use the backup from
   the database, as the only option I had was to install 2.3.1 fresh.

 * No. You can, however, install 2.2, use the backup of your database, and then 
   upgrade it to 2.3.1.

 * Righteo – I guess a new install of 2.2 may resolve the issues I had, and allow
   for an upgrade this time around… Thanks for the advice.

 * Update: Reinstalling 2.2 worked fine, however I still can’t upgrade, get a blank
   page. Thanks for the advice, never the less, reinstalling finally gave me the
   chance to export all my posts (which wasn’t possible before) so I can make a 
   clean install of 2.3.1 and import all the posts now.
