The best way it to prioritize security updates: Always apply critical security patches promptly across all systems to protect against vulnerabilities. Check if updates are compatible with existing hardware, software, and business-critical applications before deployment by evaluating compatibility. Implement a phased rollout plan, testing updates on representative systems before full deployment.

Having multiple environments is a luxury. Prepare your DSP environments (dev, stage, prod). Dev environment is where unstable but the latest code exists, Stage environment is where the stable code lives and handles various deployments, Prod environment is where stable code and deployments exist. The software update can then follow the above-tiered approach. In the worst case where you can't have all 3 environments, VM or containerized can be an option as your go-to for 'single node' validation for testing your software updates, or multi-nodes where you need to perform rolling updates.

If your software is starting to slow down, or if you're experiencing more errors than usual, it might be time for an upgrade. A business IT health check can help you identify this. Newer versions of software are often designed to be faster and more efficient than older versions.

Managing software updates across various devices and operating systems requires a careful approach. Considerations: Compatibility: Check if the updates are compatible with existing hardware and software. Security: Prioritize updates that address security vulnerabilities. Stability: Assess the stability of the update. Features: Evaluate new features that could enhance productivity or usability. Determine if these benefits justify updating. Testing: If possible, test updates on a non-critical system before rolling them out widely. User Impact: Schedule updates during off-hours to not disrupt work. Backup: Ensure that backups are in place. Policy Compliance: Follow any organizational policies regarding update frequency and approval processes.

When managing devices with different operating systems, I prioritize updates based on security, ensuring critical patches are applied immediately. I also consider compatibility with essential apps, testing updates on non-critical devices first. Performance improvements and bug fixes are evaluated to ensure smooth operation. For major updates, I wait until their stability is confirmed before applying them to critical devices. Lastly, I follow vendor recommendations and support timelines for each OS to stay current and secure.

Test updates on a small group of devices before a full rollout to catch any potential issues early.Ensure that the update will work smoothly with all systems and won't disrupt user workflow.

It depends on various factors such as the importance of the devices in question, network speed and how operating systems deal with updates. Having said that, I would suggest classifying said devices in terms of overall importance to the group/organization/company and then proceed to create a practical schedule for updating them as time allows. Of course, everyone using those devices must be aware of expected and unexpected changes at any time, meaning that the schedule you may use must be flexible enough to change at any time. Naturally, everyone's definition of concepts such as "practical schedule" will differ, which can be solved by having one or two organized meetings with key people to define said issues.
