I haven't left yet but wip. We are thinking about summer 2015.
I have a doc written by a guy who left 3-4 years ago but my neighbour who left last month says its still current and very helpful.
It basically outlines what needs to be done in what order. Apparently if you close your local account too soon you'll have some problems. This doc helps avoiding those issues I was told. I haven't read it myself yet.
If interested pm me your emails and ill happily send it out.
