Upgrades that can affect service
Some upgrades of Communication Manager affect service. During such upgrades, existing calls
are dropped and new calls cannot be established. Other upgrades preserve either connections
or calls.
If an upgrade preserves connections, stable calls, in which the talk path is established, are
maintained during the upgrade. However, new calls or call transfers from stable calls are not
processed. If an upgrade preserves calls, stable calls are maintained during the upgrade and
new calls or call transfers are processed. See Table 3: Connection and call preserving
upgrades for information on which upgrades preserve connections or calls.
