The exact command to run depends on whether or not you are copying a database to the same SQL Database server or to a different one. To create a new database (new_db) as a copy of an existing database (current_db) on the same server, simply connect to the master database then run the following statement:
CREATE DATABASE [new_db] AS COPY OF [current_db]If current_db is to be created on another SQL Database server, connect to the destination server and run this command (where source_server is the SQL Database name where current_db is stored):
CREATE DATABASE [new_db] AS COPY OF [source_server].[current_db]https://msdn.microsoft.com/en-us/library/azure/hh335292.aspx
Migrating your database is as simple as exporting the schema and data, storing this file in an Azure Storage Account, and then importing the file to create a new database. Import and Export can also be used for archiving, as well as combined with Database Copy to create a transactionally consistent copy of a database.
