CP Issue

I want to copy large amount of files aproximately more than 20,000 files from one file system to another file system, but it gives me error like:

#cd /opt/appserver/images
#cp * /opt/appserver02/public/images

Argument list is too long

Also above mention error appear again when i run:

#cd /opt/appserver/images
#chown root.root *

How can i copies & change owner of files.

This is a very common problem people ask for and the forum has several answers for this, using find with -exec or xargs for example.
