For people who have the 5TB plan, and need to use more space that 1TB, it would be very useful to transfer/migrate/move contents from one account to another. Unless you allow one account to incorporate the 1TB from the other (within his subscription plan), instead of using two different accounts. Or, unless you allow to increase the 1TB space via an additional conribution. Let's try to be more flexible with accounts within the same subscription...after all, we are paying for the best experience! Thanks!
