Is there a substantial difference between the AGSU unit patches and the old Class A patches?

The reason I ask is because I just got the AGSU and I'm getting them sewn up for BOLC. I'm finding that my actual SSI-FWTS is getting harder to find, but I do still have one sewn on my Class A jacket that's been hanging in my closet for the last decade-plus. I'm wondering if anyone would notice... or care... if I just stripped it off there for my AGSU.
