Best (easiest) way to make a SQL Server dump and import that dump in another SQL Server

I would like to achieve a database export (dump) in SQL Server from one server and import that dump in another SQL Server and not necessarily in the same schema name.

For example if I have a database prepared with all the data set for implement a new DB for a new customer, that db is for example named DB_EMPTY

And then I have to setup the same DB on some external server for a customer for example in the schema DB_MY_CUSTOMER

What is the best/simplest way to export (dump) a DB_EMPTY, and import it in DB_MY_CUSTOMER?

Possibly with SQL Server Management Studio?
