Scenario: A Citrix Administrator is managing a NetScaler SDX running eight NetScaler instances. The administrator first needs to upgrade the firmware on the instances. However, the administrator is concerned that it needs to be done all at once.
What upgrading flexibility does SDX provide in this scenario?
NetScaler SDX allows the instances to be upgraded on an individual basis, enabling different instances to run different firmware versions if required. This provides flexibility for the administrator to upgrade instances one at a time rather than all at once.
