I've tried a clean upgrade from backup several times, trying to go from 3.2.4 to 3.2.5, 3.3.0, or 3.4.0. upgrade to 3.2.5 works, but anything after that gives me this:

Sorry. A non-recoverable error has occurred.
DB Error: already exists

specifics are:

[callback] => Array
        (
           

• => CRM_Core_Error
[1] => handle
        )

   

=> -5
    [message] => DB Error: already exists
    [mode] => 16


anyone have any history with this kind of thing? I'll keep searching around.

Well, this ended up being the best advice, but I followed it poorly.

When I backed up to the previous database, I forgot to drop the data, so it was just overwriting, and leaving the superfluous tables. Once I fixed that with another proper backup, I dropped the tables:

drop civicrm_campaign_group;
drop civicrm_campaign;
drop civicrm_survey;
drop civicrm_batch;
drop civicrm_entity_batch;
drop civicrm_dedupe_exception;
drop civicrm_price_field_value;

and the install went fine. Solved!
