Why Leeds is in the middle of every current migration cycle
Leeds concentrates firms feeling current migration triggers — VMware Broadcom on legal + finance estates, Cisco end-of-life across multi-site WYCA networks, NHS WY cloud-shift, Sky Bet-class scale-up cloud-migration.
VMware → Nutanix for Leeds regulated estates
Broadcom's pricing is forcing the question on Leeds legal + finance customers. VMware → Nutanix AHV (most common in regulated), vSAN ESA, or Azure Stack HCI depending on stack preference.
Cisco → Fortinet for WYCA + multi-site retail
Leeds multi-site customers (WYCA, multi-branch retail, regional law firms) consolidating ageing Cisco onto Fortinet single-pane.
On-prem → AWS / Azure UK
Leeds tech (Sky Bet-class scale-ups) and finance customers lift-and-shifting from Yorkshire DC footprint to AWS eu-west-2 or Azure UK-South.
Exchange-on-prem → M365 for WYCA + universities
Frequent second-wave for Leeds public-sector — Exchange-on-prem to M365 GCC, on-prem PBX to Teams Voice.
What a Servnet Leeds migration delivers
Discovery + bill-of-quantities
Complete picture of the current estate turned into a migration BoQ defendable at CFO/CTO review.
Target architecture design
Reference architecture for the destination — Nutanix cluster sizing, vSAN ESA tier, AWS landing zone, FortiGate topology.
Pilot environment in week 3-4
Non-production pilot built on the new platform with two weeks of soak.
Wave-based migration with parallel-run
Production workloads migrated in waves — low-criticality first, then BAU, then customer-facing systems last.
Weekend cutover windows
For Leeds legal + finance, cutover Friday-evening onwards with engineers on-site through the weekend.
Old-platform decommission + ITAD
Once the new platform has run clean, decommission begins — chain-of-custody, NCSC-aligned wipe, certified disposal.

How a Leeds migration runs week-by-week
Weeks 1–2 — discovery + estate map
Automated discovery + interviews with application owners.
Weeks 3–4 — target design + pilot build
Target architecture signed off. Pilot environment built and non-critical workload landed.
Weeks 5–8 — wave migrations
Production workloads migrated in 4–6 waves. Customer change board signs off each.
Weeks 9–10 — soak + decom
New platform runs clean for soak. Once signed off, decommission begins.
Leeds vendor migrations — common questions
We're a Leeds law firm with 200 VMs on vSphere — Broadcom has tripled. What's right?
For most Leeds legal cluster with that footprint, Nutanix AHV — regulated-friendly, predictable per-node pricing, AHV included. Model 3-year TCO including migration — typical Nutanix payback is 14–22 months on a 200-VM estate.
Can you migrate without taking down our Sky Bet platform?
Yes — point of parallel-run. Build the new platform alongside the old, migrate betting-critical systems last, validate during off-peak hours, only cut over once your team signs off.
How do you handle Gambling Commission notification for a Leeds cloud migration?
For Gambling Commission LCCP-regulated customers we produce the technical input for the change notification — destination region resilience, control mapping, recovery plan. Your compliance team submits the formal change to GC.
Can you do Cisco → Fortinet across WYCA + 4 WY authorities with no downtime?
In most cases yes — install Fortinet in parallel, migrate sites one at a time over evening windows with rollback ready.
How long does 200-VM VMware → Nutanix take in Leeds?
Discovery → final-VM-on-new-platform is typically 10–14 weeks. Actual migration work is shorter (4–6 weeks); rest is discovery, design and soak.
We're a Yorkshire scale-up wanting to leave our Leeds DC for AWS — can you do it?
Yes — frequent engagement for Leeds tech. AWS landing-zone design, application-by-application migration, Leeds DC exit. Typical timeline 3–6 months end-to-end.
