When to install a service pack
If a service pack is available, you will need to install it in the following situations:
- After a system arrives from Avaya that does not have the service pack pre-installed.
- After a system has been installed from CD.
- After a system has been recovered using a full-backup image that did not have the service pack installed.
- After new features have been added and activated on a system. This is necessary to ensure service pack materials for the newly activated feature get installed, since the service pack package does not install fixes for features that are not present on the system.
