Sorry, I would have replied earlier, but I figured someone else would chime in for you, and I was being lazy. It looks great in the picture, and if it has been there for some time I say don't move it!
Has the color changed at all since you moved acquired it? A little more red or a little more brown? If there is an edge underneath you could frag, you could try that, but fragging it does mess up the growth pattern, and yours has a GREAT pattern. Watch the growing edges, that seems to be where trouble starts.
