SR 7.0 Upgrade Features
This upgrade to SR 7.0 allows you to create a new VM, independent of the current
VM, on the existing Cisco Unified Computing System (UCS). The SR 7.0 EC upgrade
also allows engineers to install the new SR on the new VM without having to shut
the system down until the activation of the new system software.

Cisco engineers have expended great effort to ensure that the upgrade causes
minimal system impact. However, there will be times during the upgrade where
DHCTs will be unable to boot and where some functions (BFS, billing system control
of STBs, etc.) will be interrupted. These outages will likely go unnoticed by the vast
majority of subscribers.

majority of subscribers.
How Long to Complete the Upgrade?
The upgrade to SR 7.0 is to be completed within a 6-hour maintenance window that
usually begins at midnight. All of the planning and preparation work can be done
without impacting normal operations (Chapters 2 through 4) and should be
completed before the start of the maintenance window. The maintenance window
activities begin when you stop system components in Chapter 5.
