At the end of December 2005 I upgraded my Wordpress blog to version 2 following the official procedure detailled on the codex. Unfortunately, I suppose that I didn’t do it very well, as I had many troubles with the plugins (although I desactivated all of them before perfoming the upgrade), with the new cache system…
So I decided to roll everything back to version 1.5.2 and startover again, this time using another host as a test system – this is a reason why you NEED to do a backup before upgrading!
My test system was an old HP-UX box I own, which I had to adapt into a test system: so I installed Apache+PHP and MySQL. Once this was working fine, I replicated my WP1.5 original blog to that box. This was pretty easy: I just needed to create a mysql database, import the backup of the WP1.5 blog into it. Then I copied all the files from my WP1.5 blog into that box. Finally I had to change options ‘home’ and ’siteurl’ in wp_options to reflect the new host name. That’s all!
There I started again the upgrade procedure, but this time I followed Tamba2’s guide.
This time the upgrade seem to have succeed, so I have replicated the upgraded WP2 data (files and BD) back to the production host. And there it is!
