Data-Centre Migration & Infrastructure Upgrade
Orchestrated a data-centre migration with Cisco switching/routing and Fortinet firewall upgrades using lab testing, rollback planning and UAT.
01 · Overview
A data-centre migration combined with switch, router and firewall upgrades — the kind of change where one missed dependency can take down critical services.
02 · The problem
Ageing data-centre infrastructure needed to move and modernise with minimal downtime.
03 · Objectives
- Migrate safely within agreed change windows
- Upgrade core network and security platforms
- Validate services before handing back to operations
04 · Approach & solution
Structured planning with lab validation, detailed cutover runbooks, explicit rollback criteria and UAT with application owners.
05 · Workflow
Discovery → dependency mapping → lab build → runbook → cutover → validation/UAT → hypercare.
06 · Results & impact
Migration and upgrades completed through structured planning and validation.
07 · Challenges
Dependency discovery and coordinating application owners for UAT.
08 · Lessons learned
A rehearsed rollback plan is what gives everyone the confidence to proceed.
Key features
