Drupal 6.14 is released and how to upgrade drupal 6

The new version of drupal 6, Drupal 6.14 was out. New drupal fixes some bugs and as well as critical security vulnerabilities, so upgrading is strongly recommended.

There is a upgrade instruction along with the drupal files (UPGRADE.txt), but I think it is a bit long, so I decide to rewrite it to make it shorter:

1. backup database

2. backup drupal site files

3. logon as user ID 1, place the site in Off-line mode (/admin/settings/site-maintenance)

4. if you use a custom or contributed theme, switch to core theme Garland.

5. disable all custom and contributed modules.

6. remove all old files from the drupal installation directory. and unpack the new files in.

7. copy files and sites folder back from the backup files. (copy .htaccess or robots.txt back too, if you have made changes to them. )

8. Run update.php by visiting http://www.example.com/update.php

9. Re-enable custom and contributed modules and run updata.php again.

10. Select back to the theme you like.

11. turn your site to "Online" mode. the upgrade is done.
