Hi,

the default config works - and the files are read from the
right location - there are even softlinked files present to
ensure right file is edited if you are stuck in old ways.

you cant take a 2.x config and slap it onto a 3.x server.
they are not compatible. 2 -> 3 is a re-write config task.
