I took the CSV exported from GoDaddy, striped it down to multiple lines of
domain, EPP domain, EPP domain, EPP ..
and pasted that in.
That failed.
When I removed the space between the comma and the first character of the EPP key, it worked (so far for the few I retried).
My guess is that the space confused the form parsing code. Or maybe it was just a glitch.
In any event, I've been now moving domains successfully, and in the morning I'll be re-trying the bulk of the remaining names.
BTW, in my initial retry attempt I noticed that some domains were being flagged as not transferable, something I didn't catch when i attempted to moe 30 names at once.
One name was "questionable", two others were too close to the expiration date. I got in touch with Namecheap support and they arranged to get these names transfered as well.
And once all the ducks were in a row I've been getting pretty quick turnaround times from both namecheap and GoDaddy.
So, so far so good.
I'd be certain this is intentional since those characters are ALWAYS (20+ domains transferred over a period of months) at the end of the code, although I cannot fathom the purpose since at that point you've already paid for the transfer and aren't going to give up the money you just spent.
Anybody know WTF the registrars are playing at?
