CiviCRM Community Forums (archive)

A couple months back I upgraded to Drupal 7 and CiviCRM 4.0.0. Unfortunately, Drupal 7 is much slower than Drupal 6. I would like to go back.

Now as far as I understand the codebase and db structure for 4.0x and 3.4x is basically identical, and the different versions are just for different versions of Drupal.


This is how I proceeded:

Installed a fresh install (in a new location) of Drupal 6 and CiviCRM 3.4.5. In other words, this is a Drupal codebase downgrade (from 7 to 6) but a CiviCRM codebase upgrade (from 4.0.0 to 3.4.5 which is a later version).

After the install, I dropped the CiviCRM database and imported into it my current (4.0.0) database.

I edited the version number in table civicrm_domain from 4.0.0 to 3.4.0 and then ran the upgrade script.


So far, this seems to work just fine, and CiviCRM works. As I thought, there doesn't seem to be any difference in database structure between 4.0.0 and 3.4.0 so the upgrade script worked fine and CiviCRM works fine too. I just wanted to confirm with the masters that this is OK and I will not run into unexpected problems from this.

Thanks!
