I suggest a side-by-side approach of migration of the data from test to prod environment. please follow the steps mentioned below.
1. back up your database on the test server. Check the current size of the database (both data and log file).
2. Create a database on the prodcution server using the same logical file name (as it was in test envionment) and set the defult size of the data and log file to a little higher than the log and data file size of the test environment. This will save your server resources during the restoration process.
