Is it possible to just mv /usr to another slice and create a symbolic link from /usr to the new location and have everything work as it had in its original location?

FYI: SunOS 5.9
You could. You will need to take the system to single user for this (if you run mv /usr /somewhere/else in multiuser...). So as porter suggested, test it well first so that you know exactly what you need to do during the limited downtime.

Also, there is no need to do stuff like linking /usr anywhere else. Just mount the new slice under /usr.

       /usr/ucb/ld accepts the same options as /usr/bin/ld, with the following exceptions:

       -Ldir	    Add dir to the list of directories searched for libraries by /usr/bin/ld. Directories specified with this option are  searched
		    before /usr/ucblib and /usr/lib.

       -Y LU,dir    Change the default directory used for finding libraries.

		    This option can have unexpected results, and should not be used.

FILES

       /usr/lib
