Rolling back WordPress 3.0 to 2.9.2

Couple of weeks ago, I decided to upgrade my blogging platform, the wordpress upgrade was from version 2.9.2 to 3.0.
The install was smooth as expected, but things started to go pear shaped as most of my wordpress plugins decided not to work.
It got so bad that must-have plugins were crashing my site.
At this stage it was quite obvious that my plugins weren’t compatible with the new version of WordPress.

After spending some time offloading some of the plugins and a bit of faffing around, I decided to rollback WordPress to version 2.9.2.

Here what I did

(1) Back up database using PHPAdmin and plugin
(2) Downloaded and extracted WordPress version 2.9.2
(3) Using an FTP client, I simply uploaded and replaced existing WordPress files with version 2.9.2, preserving wp-config.php
(4) Refreshed my admin
(5) That’s it

I was quite surprised that this method worked – took about 10 mins to do.
I’m sure there are better and more systematic ways to approach this. But in my case, I simply wanted to get the task done in record time.

I’m sure I’ll eventually upgrade to 3.0 in the future, but for now 2.9.2 does the job for me.
Have you had any issues with WordPress 3.0?
