Upgrading Magento from 1.1.8 to 1.5 stable

Question

Am looking to upgrade Mangeto from version 1.1.8 to version 1.5.

This is a quite a leap I am taking I know, but and I have tried the following already (as some one else had suggested on another site):

• dump v1.1.8 database, restore it in a new database.
• install magento 1.5 pointing on the restored v1.1.8 database
• let the upgrader run
• add the old theme files
• test that it all works.

When doing that, the upgrader kept saying some tables already existed.

Can anyone help me out?

Thanks

It's fine now, basically make sure you're using the same server environment.
