I’m now running here the brand new Drupal 5.0. The upgrade from RC2 was easy as I anticipated.

Here are my quick steps:

1. Login as user ID 1
2. I put my site into Offline mode.
3. Disabled couple of the contributed modules that I installed.
4. Rename my web directory to something new.
5. Backup the existing database
6. Untar the new Drupal 5.0 and rename it as the new web directory
7. Copy my old sites/default/settings.php to the new web directory
8. Run update.php from the browser
9. I copied back and reinstalled again the contributed modules that I disabled in step 3.
10. Check everything working, like changing some settings and in my case right now, try to post these steps, and see if it works :)
