I made an upgrade from 1.5beta to 1.13 which did not work very well. I had two dumps of the mysql database (with mysqldump and phpmyadmin). I was not able to reimport both correctly. What saved me was an xmldump.
Try going from 1.5 to 1.6, then from 1.6 to 1.7, from 1.7 to 1.8 and so on. It'll take longer, but it should work better.
