PunBB 1.2.20 server migration

i am going to put my PunBB 1.2.20 from test server to live server. obviously, base URL for test server is different from live server. can any one tell how to go migrate from test to live server. i mean what files needs to be copies, what database entries to change on live server etc. if u can point me to any related tutorial, what would be great.

TIA.
