I am having no luck upgrading from joomla 1.5 to 2.5 with jupgrade... I have tried everything it seems. I kept getting stuck in the decompressing stage so I went and followed the manual instructions and was able to bypass those steps. Now I'm stuck at the upgrading process getting a migrating undefined error. I am noticing that the db is getting updated with the new prefixed tables but the third party components/plugins are not getting converted. These tables are also empty so no migration is taking place. It is like it is getting half way through and then getting stuck on something.

I have tried everything suggested here: http://wiki.redcomponent.com/index.php?title=jUpgrade:Troubleshooting

PHP Fatal error:  Uncaught exception 'Exception' with message 'Duplicate entry '62' for key 'PRIMARY' SQL=INSERT INTO `j25_users` (`id`,`name`,`username`,`email`,`password`,`usertype`,`block`,`sendEmail`,`registerDate`,`lastvisitDate`,`activation`,`params`)

This is the error I'm getting now. I still get migrating undefined on the users table but then it moves on and then get hung up on 3rd party extensions. My problem is I have gone into the table manually and investigated for the dup but there isn't one. I even deleted the user and am still getting the error.

Any ideas what I should do? Advice. Thanks

In my experience (a dozen sites migrated) the cause is often different, just check the error logs. Usually the issue lies with an extension that added fields to #__content or another system table. Read the logs.
