I bought a custom theme, tweaked it out, added content, uploaded images and got the whole site running the way I want. I have done this all on a test-domain. Now I want to get it all onto the actual domain.

Can I just FTP every file on my computer and then FTP them all back to the actual domain and have the site work? Or will it break in the process?
Do I ahve to go back and re-do each and every little tweak and everything?

I have always done it on the actual domain it was going on, but this time I couldn't.

Any one know?
