The migration path is painless (at least for me) and it works pretty much straight away with little problem. I am a happy camper and in my opinion my blog now has a better address compared to the old scheme.
Only comment is that I think the migration timetable is rather short from the time of the migration path released to the end of FTP publishing. Having said that I think this is due to Blogger trying to close this project as soon as they can.
All in all I think the migration tool works and works very well and the move to FTP publishing to Blogger's hosted blog is better since it seems that their web server is much faster than my free GoDaddy's one :)
