Estimated Timeline
The upgrade to SR 5.0 features the Solaris Live Upgrade which provides the ability
to “stage” an area on disk with the upgraded operating system and application
software prior to entering the maintenance window.
Most sites should be able to complete an upgrade within a typical 6 hour
maintenance window. However, depending on the size of your system, it could take
longer. Key factors are the size of your database and the number of headend
elements.
Post upgrade procedures involve resetting the modulators. Our engineers
recommend that you never reset more than eight modulators at once. Refer to the
following table for estimated times for resetting the modulators.
