Deployment story
Legacy Dell networking to Juniper
Replace aging Dell network equipment with a Juniper design that is easier to manage and ready for the next stage of the business.
← All stories and scenariosThe challenge
Build around the work.
A legacy Dell switching environment from the pre-Force10 era needed a more manageable foundation. The opportunity was to improve how the network was operated while putting the replacement investment toward capacity, resilience and future growth.
How the solution fits together
Juniper EX for access and campus switching · QFX for appropriate aggregation or data-center roles · SRX for security and routing
Products and software
- Juniper EX Series and Junos OS ↗
- Access and campus switching with consistent configuration and operating practices.
- Juniper QFX Series ↗
- Higher-capacity switching for the aggregation or data-center role selected in the design.
- Juniper SRX Series ↗
- Firewall policy, segmentation and routing at the required network boundaries.
- Juniper Mist Wired Assurance ↗
- An option for centralized onboarding, visibility and troubleshooting on supported switches.
What we do
- Map the existing ports, VLANs, uplinks, traffic and dependencies before selecting replacement hardware.
- Build consistent configurations, document security boundaries and stage a migration with rollback.
- Connect configuration backups, monitoring and operating documentation to the team that will support the network.
Why it matters
The return comes from a network that is easier to understand, change and support, with capacity placed where it is needed. Evaluate the investment against support effort, recurring costs, service interruptions and the useful life of the replacement design.

How we verify it
Compare application performance, uplink utilization, recovery behavior and routine change effort before and after the migration. Record the hardware, licensing and operating costs used in any ROI calculation.
