Is Multi-Region Possible?
It is possible to have multiple regions under a group, but it is not possible to have multiple regions under one account.
NOTE: There is not a way to transfer data from one region to another. An account will need to be created in the new region and the data will have to be re-uploaded to this new account.
You can manage multiple accounts in different regions by placing those account inside of a unified Group. To create a group please see the instructions here: Creating a Group FAQ.
