Hello:
I'm trying to upgrade my drupal civi to a newr version. My only success is from 2.1.4 to 2.1.6.
After that I'm trying to go to 2.2 and I receive this error:

Sorry. A non-recoverable error has occurred.

DB Error: a515ac9c2796ca0e23adbe92c68fc9fc

Database Error Code: Error on rename of './civicrm3/civicrm_participant' to './civicrm3/#sql2-6522-507' (errno: 152), 1025

Any guidance will be highly appreciated. I invested all the afternoon on this. A manual upgrade explanation is also good for me.

Thanks!

For anyone upgrading an old DB through 2.x series, I ran into this while consulting on an upgrade recently.

In the 2.1.6 DB which was being upgraded, a couple of keys were not *foreign* keys, so DROP FOREIGN KEY would fail.

I also found that fields which the upgrader tried to add to civicrm_event were already present.

This could easily be specific to the site which I was upgrading, but I've posted the diffed code for v2.2.9 for anyone who hits similar in future.

(Also saw some other silly issues - duplicated tables preventing creation of FKs because the FK name was already assigned, and for some ungodly reason the DB version in civicrm_domain was 2.11 - a version of CiviCRM which never existed.)
