I would get into the habit of using the new site moving forward, especially for PayPal payments. PayPal won’t work with the old site.
And we’re going to retire the old site sooner rather than later, so please keep that in mind.
Transfers are not functioning for some folks and this is a known issue.
There’s little support can do about the transfers at this moment, I’m sorry. 
TSW would be the exception here, as far as I’m aware. At some point in the future, we intend to retire the old AO and AoC register-dot account pages in favor of the newer account-dot sites.
