File1 contains a single disk for system files and two SCSI hard disks that comprise a 72-GB mirrored volume with 65 GB of read-only data. Users connect to this data by using shortcuts on their desktops. File1 is scheduled for replacement. You have a scheduled maintenance window to complete this task. Before the maintenance window, you build a new server. You need to bring the new server online with current data and re-establish redundancy as quickly as possible. You must also ensure that the desktop shortcuts will continue to function. What should you do? ()
