I have been slowly switching over the last year... My tank is that if something is wrong, your Softies will tell you now... if you wait, it takes about 2 weeks for the hard coral to tell you.
I moved my Mont, Capricornious up higher when I had compacts because they can from someone who had brighter lights... 6 months later I plugged in my new hallides... It took 3 weeks before I noticed the color was slowly bleaching out. I have now moved them lowed, and the are coloring up again.
Like this...
