Ballast upgrade; need new socket?

I have a 250w ballast and bulb setup.
The socket is already mounted into a cooltube.
There is a chord that connects my socket into a ballast.

I'm considering using the cooltube for a 400w setup.

Can I just plug that same socket/chord into a new 400w ballast box and screw in a new 400w bulb into my existing socket.

Or do I need to upgrade the chords and socket as well (to handle increased wattage)?
