Vendor migrations in Leeds —
VMware, Cisco, on-prem to cloud, done safely.
Servnet runs parallel-run vendor migrations for Leeds businesses facing Broadcom-era VMware pricing, Cisco end-of-life, on-prem to cloud lift-and-shift. Discovery → pilot → migration waves → decommission. Leeds cutovers happen Friday-evening to Sunday so Monday open is clean across the legal cluster, Yorkshire finance, and NHS WY estate.
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.
