That is how I do my maintenance/migrations too. When I need to move from 5.3 to 5.4, I create alternate mdisks in the production systems (VMARES, VMLR ES) and copy the stuff from 540RES to the alternate mdisks. Then on cutover, I use dirmaint to switch the production and alternate mdisks. If I need to revert, I use dirmaint to switch the mdisks back. The exception is the CP
Nucleus. I can put that out on the production config disk with a unique n ame (CP54NUC MODULE) and use the SAIPL process to ipl with this alternate nucleus until we are satisfied with it. /Tom Kern /U.S. Dept of Energy /301-903-2211 On Mon, 10 May 2010 13:23:27 -0400, Karl Kingston <[email protected] > wrote: >We're running z/VM 5.3.
