Collector's edition items in my standard edition character?

You need to register it to your service account. But every platform version can only be registered once.
You can also simple upgrade your standard account to a CE account on Mogstation.

Hey. Thanks for the info.
When I log in on my PS3 it asks me which item to register so I choose the Collector's edition and it shows me Service Account: FFXIV and Service Option to be added and everything is there but underneath there is a square saying Create a New Service Account.
Although there's even a warning saying;
"If you would like to import pre-existing character data, please do not select this option".
Above it though it tells me that by registering a new service account I will be unable to import characters created on a different platform. So I worry I won't be able to take Quenn with me.
