I was looking for the first time move also – what do we do?
copy everything on server, create backup of staging database and then? what files to change (because database settings of server, where PW2 was installed and developed (either dev or local) probably has different settings than live server)
And in addition, there are people (like me), who use shared hosting for some sites (in here, it's much more efficient in speed, price and reliable than cheap virtual), so they might not be ssh
but the part of copying data between servers is the less important – moving from staging to live for the first time it's important! (i.e. in wordpress, you have to backup, edit and copy files in selected order, otherwise you have a problem)
