So which is more painful:
Keep the current Networker v7.2.2 and downgrade the kernel to RedHat ES 3 or
Keep the current kernel of Red Hat ES 4 and upgrade Networker to v7.3.x

If you check the NetWorker hardware compatibility guide, you will find 
that NetWorker 7.2.x is not supported on Red Hat ES 4.  NetWorker 7.2 is 
only supported on Red Hat ES 3.

Red Hat ES 4 is supported for NetWorker 7.3.x
