Subject:        Upgrade process - 1.2rc1 from 1.1RC1

Hi Guys,

I realise I've sent a few queries on this, just trying to keep all data together.  Got an exception while processing one of the documents.  I think it could be MySQL timing out though?

I should point out that a clean, new install of 1.2rc1 works perfectly for me.  Just upgrading from 1.1 seems to be a bit dodgy for some reason!
