Upgrading from previous versions

This chapter contains articles that discuss the upgrading process of your drupal installation.

Please note that comments are not meant to address problems you found during installation. For problems with installation, please address your questions to proper places. Before upgrading Drupal core you might need to convert custom modules and convert custom themes.

Drupal 4.7.x and earlier are no longer officially supported and should be upgraded to a supported version.

NOTE: One of the most IMPORTANT things to do BEFORE you upgrade, is to backup your sites files and database. See this example of an automated backup script.
