Provided the full script for copy between subscriptions

Customers open a lot of support requests for copy between subscriptions. The finding the SID part might not be something they are familiar with. I have at least handled 10 customers with the same ask and I have always provided this script. It is better to have it in the doc itself to avoid support requests.

 You can use the steps in the [Copy a SQL Database to a different server](#copy-to-a-different-server) section to copy your database to a server in a different subscription using T-SQL. Make sure you use a login that has the same name and password as the database owner of the source database. Additionally, the login must be a member of the `dbmanager` role or a server administrator, on both source and target servers.
 
+```sql
+Step# 1
+Create login and user in the master database of the source server.
+
+CREATE LOGIN loginname WITH PASSWORD = 'xxxxxxxxx'
+GO
+CREATE USER [loginname] FOR LOGIN [loginname] WITH DEFAULT_SCHEMA=[dbo]
+GO
+
+Step# 2
+Create the user in the source database and grant dbowner permission to the database.
+
+CREATE USER [loginname] FOR LOGIN [loginname] WITH DEFAULT_SCHEMA=[dbo]
+GO
+exec sp_addrolemember 'db_owner','loginname'
+GO
+
+Step# 3
+Capture the SID of the user “loginname” from master database
+
+SELECT [sid] FROM sysusers WHERE [name] = 'loginname'
+
+Step# 4
+Connect to Destination server.
+Create login and user in the master database, same as of the source server.
+
+CREATE LOGIN loginname WITH PASSWORD = 'xxxxxxxxx', SID = [SID of loginname login on source server]
+GO
+CREATE USER [loginname] FOR LOGIN [loginname] WITH DEFAULT_SCHEMA=[dbo]
+GO
+exec sp_addrolemember 'dbmanager','loginname'
+GO
+
+Step# 5
+Execute the copy of database script from the destination server using the credentials created
+
+CREATE DATABASE new_database_name
+AS COPY OF source_server_name.source_database_name
+```

 > The [Azure portal](https://portal.azure.com), PowerShell, and the Azure CLI do not support database copy to a different subscription.
