Off-line Software Upgrade

Restoring the Previous (Pre-online Upgrade) Software Image

If for some reason you need to restore the system to the software image that was running before the online
upgrade process, perform the On-Line Software Upgrade again and specify the locations of the original
software image and configuration files.
Off-line Software Upgrade
An off-line software upgrade can be performed for any system, upgrading from any version of operating
system software to any version, regardless of version number. This process is considered off-line because
while many of the steps can be performed while the system is currently supporting sessions, the last step of
this process requires a reboot to actually apply the software upgrade.
This procedure assumes that you have a CLI session established and are placing the new operating system
image file onto the local file system. To begin, make sure you are at the Exec mode prompt:
[local]

Configure a Newcall Policy

Configure a newcall policy from the Exec mode to meet your service requirements. When enabled the policy
redirects or rejects new calls in anticipation of the chassis reload that completes the upgrade process. This
reduces the amount of service disruption to subscribers caused by the system reload that completes the upgrade.

Newcall policies are created on a per-service basis. If you have multiple services running on the chassis,
you can configure multiple newcall policies.
