How can administrators ensure minimal disruption during ISE updates?

Applying updates during off-peak hours is a strategy that significantly minimizes disruption for users and ensures system performance is maintained. During off-peak hours, there are typically fewer users accessing the network, which reduces the risk of interruptions to critical services and functions. This approach allows administrators to complete necessary updates while limiting the impact on the daily operations of the organization. Additionally, performing updates when usage is low can facilitate easier troubleshooting and give staff the opportunity to monitor the update process without the pressure of peak activity levels.

The other strategies would not effectively achieve minimal disruption. Randomly applying updates at any time can lead to unexpected issues during high-usage periods, potentially causing service outages. Setting up a maintenance window during summer could be ineffective depending on the organization’s operational calendar, as summer might not correspond to low usage, especially for businesses that operate year-round. Postponing updates indefinitely might leave the system vulnerable and can compound issues over time, ultimately leading to greater disruption in the future.
