Active Upgrade splits the system into two independently running systems (split mode).
During upgrade, one side of system (CPU/IO module) continues to run application (Production Side), while the
other side of system (CPU/IO module) upgrades software (Upgrade Side).
Upon completion of software upgrade, the Production Side system runs synchronously with the Upgrade Side
(merge mode).
