Network Cutover Overview
A network cutover is a critical event in networking projects, marking the culmination of planning, staging, testing, and configuration activities. While cutover types and activities may vary, there are fundamental principles that apply to all network cutovers.
- Discovery: Successful network cutovers begin with comprehensive network discovery. The depth of discovery depends on factors like familiarity with the network, cutover type, and technology involved. Collecting detailed information upfront, such as VLANs, credentials, SNMP strings, ACL locations, routing configurations, IP addresses of critical resources (DHCP, DNS servers), and more, is crucial to avoid last-minute scrambling or issues during the cutover.
- Planning and Testing: After gathering the necessary information and studying the network topology, it's time to plan the cutover activities. When possible, recreating the customer's topology in a lab environment using tools like GNS3 can be invaluable for testing and validating changes before implementation.
- Staging: Staging devices and configurations can significantly reduce work during the change window and minimize network downtime. For example, setting up new core switches in an adjacent rack to the production switches, carefully trunking the old switches to the new ones, and gradually migrating distribution switches, VM hosts, and other components over several days or weeks.
By following best practices for network discovery, planning, testing, and staging, organizations can streamline network cutovers, mitigate risks, and ensure a smooth transition during critical network changes.
For comprehensive training on network engineering services, network cutovers, and related technologies, consider enrolling in courses offered by SPOTO Club, a reputable provider of IT certification training with a team of experts and a proven track record of success.
