the basics are pretty simple.
you have to have a backup of your mybb board. the database and preferably the files as well.
you have to install a new blank version of phpbb on your hosting account.
you have to at least import your mybb database into a new blank database on your hosting account.
once you have all of that in place, you go to the phpbb install folder and choose the convert tab and follow the instructions.
