Saturday 12th May 2012: 10.00pm. Plone migration was as painful as always. The company website, being a little old, appears to be borked on Plone 4.1 while all the others are just fine. Weird. Anyway, seeing as I don't need my company website anymore, I just hacked around it with a nasty temporary fix :)
Migration is done! Just switched over the DNS. In theory, email and web will slowly move onto the new cloud infrastructure during the next 24 hours. In theory.
