Move Photo library to new Apple ID
I want to establish a separate Apple ID account in the country to which I migrated in 2017 (Australia), while still maintaining my account in my country of origin (USA). I would like to migrate or import my Photos from the USA-based Apple account to the new Australia-based one.
I intend to do this on my MacBook Pro, where I am now maintaining two logins, one for each of those two Apple ID accounts.
Is this possible? If it is, is it as simple as copying the Photos library to an external drive and then importing the contents to Photos in my new account? If not, how?
Thanks very much
MacBook Pro 13″, macOS 11.3
