Scenario: A Citrix Administrator is managing a Citrix ADC SDX running eight Citrix ADC instances. The administrator needs to upgrade the firmware on the instances. However, the administrator is concerned that it needs to be done simultaneously.
What upgrading flexibility does SDX provide in this scenario?
Citrix ADC SDX provides the flexibility to upgrade Citrix ADC instances on an individual basis, allowing each instance to run independent firmware versions. This means that the administrator does not need to upgrade all instances simultaneously, and each instance can be maintained and upgraded separately according to specific needs.
