How can we update ThreeJS version 'r163' for nunuStudio?

I want to update from threejs version 119 to r163 for nunustudtio, how can I do this.

You’ll need to clone the nunu studio repo and update the three.js version in package.json, then go through the steps in the migration guide.
Going straight from r119 to r163 is probably a bit too quick, so I’d try updating THRE to something like 125, then 130 etc. and pay special attention when you get past r150 as there are a lot of updates to lighting / color stuff.
