Comment 5 for bug 1495064

Yes I guess it is an ordering issue. Some new on my recovery investigation:

* I have installed from scratch on a test system 1.5.4 1.7.6 and 1.8.0 (no upgrades) and in each case the migrations all happened successfully as expected.
* The database structure at the point of failure seems pretty close to the 1.7.6 but yet to double check.

I am about to attach SQL dumps of the 1.5.4, 1.7.6 and 1.8.0 *empty* databases, and a schema only update of the local database as of the interrupted upgrade. Also the last steps of installation for 1.5.4 and 1.7.6.
