Should I delete my PhotoshopCC?

I downloaded the 2014 upgrades to Photoshop, Lightroom and Bridge.

I now have TWO Photoshop icons on my iMac - the Photoshop CC and the (new) Photoshop CC 2014.

Should I delete the Photoshop CC and how should I do it?

(Incidentally, the PhotoshopCC had a bunch of third party plugins (OnOne, Topaz etc) which will now have to be reinstalled on the PSCC2014 - pain!)
