Copy Azure Sql Database from one subscription to another

Please let me know how to make a copy of azure sql database which is present in another azure subscription.

I could not find Server objects in SSMS to create a linked server, please advise if server objects will not be available for azure sql. When I tried CREATEDATABASE Database2 AS COPY OF server1.Database1; I get error message as Msg 45134, Level 16, State 1, Line 1 The remote partner server name 'source server name' could not be resolved. Please provide valid partner server name.
