After an OpenVMS I64 system shuts down, you can use the
OpenVMS I64 Boot Manager utility to add and validate a boot option
for the newly upgraded system disk, and then boot the newly upgraded
system disk. AUTOGEN runs automatically, after which the system shuts down again
and automatically reboots. If you are doing a concurrent or rolling
upgrade in an OpenVMS Cluster environment, do not boot any other
cluster members now.
Now go to Chapter 7 and check for any postupgrade tasks that
need to be performed before the system and cluster can be used. Once
you have completed all required postupgrade tasks, you can reboot
and then use other cluster members.
