That'll leave the hot cylinder full, look for a drain point at the base
of the cylinder where the cold enters, or failing that you may need to
undo the threaded connection at the top where the hot exits, and syphon
it with a hose.

Whatever you do, don't close the inlet valve to the hot tank, and
open the kitchen hot tap. This can be an effective, but costly,
way to demonstrate the power of atmospheric pressure.
