What is the backup supposed to do? Usecase - transfer profile to a new handset?

Reading this thread here:

It appears that I should not expect the Backup/Restore functionality to cover the usecase of transerring Contacts to a new SFOS handset.

Rather I should use the System Setting > Apps > Contacts > Import function.

And since I will be selecting “Other” rather than “Android” or “Iphone” I will need to import Contacts via vCard file(s).

How does one create an export of the Contact records in vCard file(s) format on my existing XA2 Plus, such that I may trasnfer them onto the new 10 iii?

Many thanks
