Technology evolves rapidly—and so must your network. A well-timed and thoughtfully executed network refresh ensures optimal performance, reduces security risks, and supports business growth. But when should you refresh your infrastructure, and how can you do it without disruption? This article breaks down the strategies, timing, and best practices for a successful network upgrade.
A network refresh refers to the comprehensive upgrade or replacement of networking equipment such as switches, routers, firewalls, access points, and cabling. This process ensures your infrastructure meets modern performance, security, and scalability standards. It typically involves:
Manufacturers regularly announce end-of-life (EOL) for hardware. Once this happens, support, firmware updates, and security patches stop—leaving your business vulnerable. Cisco’s EOL product list is a useful reference.
If users frequently report slow connectivity, dropped connections, or issues with VoIP/video conferencing, it’s a clear sign that your current network can't keep up with demand.
Outdated network hardware is more susceptible to vulnerabilities. Modern firewalls and switches often have built-in security features to help mitigate cyber threats.
Expanding business operations often requires scalable infrastructure. Moving to a new office is an ideal time to reassess and deploy newer technology.
New business applications, IoT devices, and cloud services demand high bandwidth and low latency. Legacy networks simply aren’t designed to support these requirements.
Start by auditing your current infrastructure. Identify what devices are nearing EOL, what’s underperforming, and where bottlenecks exist. Tools like SolarWinds Network Performance Monitor can help.
Is your goal to increase speed, enable remote work, strengthen security, or support cloud adoption? Your refresh strategy must align with specific business goals.
Plan based on both CAPEX and OPEX models. Consider the cost of hardware, licensing, labor, downtime, and future scalability. A well-planned refresh can reduce long-term maintenance and energy costs.
Choosing the right vendors is critical. Evaluate offerings from industry leaders like Aruba Networks, Fortinet, Cisco Meraki, and Juniper to match your infrastructure needs.
Develop a phased rollout strategy that includes test environments, off-hours maintenance windows, and rollback plans to minimize disruption.
Create an accurate inventory of all devices, IP mappings, VLANs, and configurations. Tools like ManageEngine DeviceExpert simplify this process.
Reassess your network topology. This is an opportunity to adopt better design principles such as segmentation, high availability, and SD-WAN.

Test new equipment in a controlled lab environment to evaluate performance, compatibility, and manageability before a full deployment.
Divide the implementation into manageable phases—start with non-critical segments before moving to core infrastructure. Monitor performance after each stage.
Post-refresh, continue to monitor performance and user feedback. Refine configurations and optimize bandwidth allocation for peak performance.
Network upgrades can be overwhelming. Many businesses partner with IT service providers like InterDataLink to manage everything from planning to deployment. Our team ensures minimal downtime, full documentation, and post-installation support.
