Shoot it and find out. You ain't going to see much difference in height until you shoot at least 30 yards. It only changes your speed about 5fps. Probably just gang adjust unless you shoot longer.

For example, just today I was shooting an indoor 3D with arrows 65grains heavier than my sights are set for. At 20 yards there was only about 1" difference in elevation. My speed went from 295fps to 270fps and all I had to do was change my ming. Instead of my pins hitting right on at 25,35, and 45 yards they were hitting at 20, 30 and 40 yards. I didn't change the sight at all. I just changed my thinking.

You have to shoot it. Your bow needs to be retuned.[&:]

I thought this was going to be a draw weight thread.

You will need to reset all your pins. You have picked up a good bit of speed and the diameter of the carbon will probably be less than the aluminum. This will require either rest and/or nock set adjustment.

Dropping your point weight will have the effect of stiffening your shaft.
Not always a bad thing.

Anyway, it may or may not seriously affect your tune.
It depends on where your current arrow's spine value lays within the adjustment capabilites of the rest of your setup.
If you were shooting right near the edge of it before, then something will have to change.

First shoot it and see, but if your paper tune was good before, you'll probably see a right tear with the 100s.
If it is small, try shooting field points vs broadheads for point of impact comparison at several distances.
That will tell you how bad it really is.

If you're not satisfied...
Try moving the rest left (if you're right handed), raise the draw weight, buy new weaker spined arrows, or go back to the 125s.

Don't worry about making any changes to your sights until after you have the arrows flying right.
That should always be the last adjustment, as they have nothing to do with proper flight, and will not help you make good hits when your arrow is fishtailing or porpoising. Penetration is also gained with a good tune since all of the arrow's energy is directed in a straight line driving the point forward.

Good luck.
