Here's a more detailed and technical breakdown of the process: Communication and Approval: Inform stakeholders, including managers, customers, and relevant parties about the planned upgrade activity. Seek their approval and ensure everyone is aware of the potential impact. Service Analysis and Preparations: Identify all services that could be affected by the upgrade across your infrastructure. Collaborate with service owners to perform pre-checks and post-checks on the day of the upgrade. Request service owners to conduct necessary validations and ensure service continuity. Account Management: Obtain local account credentials for all devices slated for upgrade. Avoid reliance solely on external authentication systems like RADIUS or LDAP to ensure uninterrupted access during the upgrade process. Planning and Approval: Develop a comprehensive plan encompassing pre-checks, post-checks, and rollback procedures. Seek approvals for the planned activities and ensure alignment with change management processes. Engage technical support resources for assistance and have them on standby during the upgrade. Technical Validation: Validate the upgrade steps with the technical support team to address any potential issues or concerns. Incorporate feedback and suggestions from the support team to refine the upgrade plan. Backup and Configuration Management: Take backups of device configurations to facilitate easy restoration in case of unforeseen issues. Ensure that configuration backups are securely stored and readily accessible during the upgrade. Execution Phase: Prioritize thorough pre-checks, dedicating ample time to identify and resolve any potential issues before proceeding with the upgrade. Coordinate with other service owners to ensure comprehensive backup procedures are followed. Execute the upgrade activity according to the approved plan, adhering to established timelines and procedures. Post-Upgrade Validation: Conduct post-upgrade checks to verify the successful implementation of changes. Enlist the assistance of relevant stakeholders to perform additional validations. Address any issues identified during post-checks promptly through troubleshooting measures. Rollback Procedures: In the event of significant issues or uncertainties regarding recovery within the change window, initiate rollback procedures. Execute rollback measures as per the pre-defined plan to restore previous configurations and ensure service continuity.
The key to a successful network upgrade is preparing all employees for a potential down period. I made this mistake recently -- while my IT professionals assured me the downtime would be minimal, it stretched on longer than expected, and unfortunately, I hadn't adequately informed lower-level workers. This was my own bias: I focused on client-facing employees, when I should have pulled everyone in for a meeting. It's easy to forget that in this day and age, the entire office relies on connectivity, and even an hour or two offline can be detrimental. So, if I do this again, I'll know to better prepare the whole office for the worst case scenario. Linn Atiyeh Founder & CEO, Bemana https://www.bemana.us/practice-area/industrial/
Taking the helm for a significant network upgrade at our company, I applied the principle of "divide and conquer". Every department was assigned a role based on their expertise, which not only encouraged an inclusive and collaborative environment but also ensured that every cog of the organizational machine was well-oiled and prepared. If I was to share a kernel of wisdom with someone embarking on a similar journey, it would be this: Don't shy away from leveraging the diverse talents present in your organization. It aids not just the efficient division of labor but also helps foster a camaraderie that's absolutely essential when navigating the choppy waters of a network upgrade.
