Migrating from Drupal 6.x to Acquia Drupal
This chapter covers migrating an existing Drupal 6.x site to Acquia Drupal.
Acquia Drupal SVN repository - If you want the easiest and most reliable site maintenance possible (and to avoid most of the following "manual" update procedure), you should update to the version of Acquia Drupal in Acquia's SVN repository on your local machine or remote server. Alternate instructions are included in the D6.x to Acquia Drupal: Advanced Migration with the Command Line - SVN Repository section of this guide. Note that SVN maintenance is only possible from the command line, not using GUI + FTP tools.
