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.
It should *always* work to make a direct upgrade from the old version to the new version. If it does not, that is a bug and we need to *find out why* and *fix it*.
Making multiple upgrades with intermediate versions is *more* likely to cause trouble, because the old intermediate versions might themselves be buggy, or fail to properly work with your new PHP or MySQL version.
1) Back everything up first.
2) No, really. Back everything up first. :)
3) Run the updaters *to the current version* and *save ALL output* from the updater script. Just running it a second time will *not* give you the same information.
4) If you have problems, provide *all* of that information when seeking help.
