I just noticed that this is a one-time occurrence after the move to a new network. In this case there is no need to schedule the at job. Just make a backup of files you are changing, then make the changes. They will not take effect immediately unless you restart any of the services. (So don't restart an services or reboot the server prior to the move.) Plan a time to make the changes prior to shutting down at the old data center. They should come up correctly in the new environment. c
