Kudos to the +Google Play
developer support team!
A few weeks ago I got slightly freaked out by the stories floating around that developers who have apps that infringe the Play Store policy got locked out of their personal Google account, when that's the one they registered as a developer account.
So, I created a new dummy Frisbeeworld Google account. I used that to create a new Play Store developer account (including paying the $25 fee). Then I added my personal Google account as an administrator to the developer account. Easy enough.
Next step, migrate "all" my apps (two of them) from the previous account. Google provides a web form for doing that, I just needed a few bits of info from my previous developer account and then I submitted. Within eight hours, I had an email from Amy at Google Play Developer Relations notifying me that my apps (and all their statistics) had been migrated. She also suggested I reply to the email if I wanted my original developer account fee refunded. I did and they refunded my $25 within a couple of days.
