The Problem
What the client faced
A pan-India enterprise client with aging network infrastructure needed a modern Wi-Fi 6, SD-WAN and firewall stack across 5 offices — but demanded zero business downtime and no impact to customer-facing systems.
Our Solution
How SUKAI delivered
SUKAI engineered a parallel-run architecture where new infrastructure was deployed alongside legacy systems, tested end-to-end during off-hours, and cutover in phased windows. Each cutover was accompanied by 24/7 hyper-care support for a week.
