Updating NT Applications
The key to upgrading NT Applications is to make sure the upgrade is
performed on the proper machine. All array applications run on the
CE operating system. Generally, applications are upgraded using a
CDROM. Since the CE does not have it's own CDROM, a
redirected CDROM must be used. An alternative to this method is to
use a Network Shared CDROM.

Upgrading of any application in a high availability should be
preceded by testing to ensure the stability of the upgrade.
If the application upgrade requires a system reboot then the CE NOS
will have to be rebooted. Do not allow NT to reboot the CEs.
Instead, use the Marathon Manger to issue a reboot sequence for the
CEs.
