Transfer one wordpress site from test server to real server

Hello I designed a website under my domain using a subdomain for a test environment now I have everything completed I was told that I could use Updraft plugin that is free to backup my website and then restore it to the real hosting server, my problem is Updraft for free does backups not migrations for free.  Does anyone have a free option to migrate my theme and complete WordPress site over to another domain name and sever?
