Network Migration Consulting

🚨 Is Your Network Ready for the Future? Or Stuck in the Past with IPv4? One of the biggest blind spots for many TELCO and IT decision-makers today is the delayed migration to IPv6. 🧩 While IPv4 has served us for decades, it’s now holding us back: ▫️ We're out of new IPv4 addresses. ▫️ NAT and CGNAT are increasing complexity, latency, and security gaps. ▫️ IPv4 isn’t scalable for 5G, IoT, or modern cloud-native architectures. The result? Higher operational costs, limited scalability, and fragile user experiences. ✅ So, what’s the way forward? IPv6. ▫️ Migrating to IPv6 isn’t just a technical upgrade — it’s a strategic decision that: ▫️ Unlocks virtually infinite address space (2^128). ▫️ Eliminates NAT, reducing latency and simplifying design. ▫️ Enables next-gen services: 5G, IoT, SDN, Zero Trust, MEC, and beyond. ▫️ Enhances routing efficiency and global interoperability. 🚀 Migration Strategy Highlights: ▫️ Start with Dual Stack: IPv4 + IPv6 coexistence. ▫️ Use Tunneling or NAT64 for transitional phases. ▫️ Target IPv6-only for mobile, cloud-native, and greenfield deployments. Yes, it requires: ▫️ Investment in upgrades, ▫️ Training for your ops team, ▫️ And extensive testing... But the cost of inaction is far greater. 👨💻 I’m Carlos Luis Prieto Jiménez - TELCO — Optical | IP | Networking Expert I’ve helped companies optimize their network backbones, reduce downtime, and modernize infrastructure — including guiding successful IPv6 transitions. 📩 If you're a recruiter or technology leader looking for someone who doesn't just understand the problem — but solves it — let's connect.

Drawing on many years of experience in #DNS, #DHCP, and #IPAM, I have decided to contribute back to the community by sharing a set of resources designed to support the structured planning and execution of #DDI initiatives. The workshop helps identify the current situation and define the desired target state (cf. https://lnkd.in/eiwpYUyb ), the questionnaire supports selecting the right solution to achieve that target state (cf. https://lnkd.in/eQZJS59V ) and the migration plan ensures a smooth and well-documented transition from the existing setup to the new environment (cf. https://lnkd.in/eFexa_Ka ). I hope these materials are useful to anyone managing network services or planning to modernize their infrastructure.

Colgate-Palmolive ran everything through SAP - from factory floors to dentist offices. When I led their migration, one thing was clear: this wasn’t just about moving systems. It was about keeping a global supply chain alive. Back in the early 2000s, I was consulting on one of the most high-stakes SAP migrations I’d ever faced. Colgate’s global operations depended on a single truth: If SAP goes down, so does everything else. Toothpaste doesn’t show up on shelves. Distribution centers stall. Orders to Walmart, Walgreens, and CVS? Delayed. The supply chain goes silent. I remember thinking, “This isn’t about software anymore. This is a logistics problem with a technical disguise.” So before we moved a single bit of data, we did what most teams skip. Here’s what our playbook looked like: 1. Inventory the unknowns We scanned every system — not just for size, but interdependencies. You can’t move System A if B, C, and D are chained to it. 2. Model the risk How much data? How long would each copy take? Where were the bottlenecks — disk IO, network bandwidth, or just legacy bloat? 3. Rank criticality by impact, not size Some “small” systems had outsized business value. Like the one tracking global SKUs. Touch that wrong, and orders get lost in translation. 4. Simulate the move — multiple times We did dry runs. Timed every process. Tweaked our scripts. Even ran scenarios for “What if this breaks mid-flight?” 5. Coordinate like air traffic control Every migration phase was mapped like a flight plan. Timelines, dependencies, failovers. No guesswork. No egos. That project worked. No disruptions. No delays. No headlines (which, in IT, is a win). It also planted the seed for what would eventually become IT-Conductor Inc. Because I realized: Migrations aren’t about tools or timelines. They’re about orchestration. And orchestration starts with a brutally honest assessment. If you're facing a cloud migration and feel unsure where to start — start there. That’s what separates a clean cutover from a career-defining disaster.
