Vendor migrations in Bristol —
VMware, Cisco, on-prem to cloud, done safely.
Servnet runs parallel-run vendor migrations for Bristol businesses facing Broadcom-era VMware pricing, Cisco end-of-life, on-prem to cloud lift-and-shift or platform consolidation. Discovery → pilot → migration waves → decommission. Bristol cutovers happen Friday-evening to Sunday so Monday open is clean across Temple Quarter fintech, Filton aerospace and BNSSG NHS.
Why Bristol is in the middle of every current migration cycle
Bristol concentrates firms feeling current migration triggers — VMware Broadcom on Temple Quarter fintech estates, Cisco end-of-life across multi-site WECA networks, NHS BNSSG cloud-shift programmes, Filton aerospace consolidation onto HCI.
VMware → Nutanix for regulated Bristol estates
Broadcom's pricing is forcing the question on Temple Quarter fintech and NHS BNSSG customers. We run VMware → Nutanix AHV, vSAN ESA, or Azure Stack HCI depending on customer stack preference.
Cisco → Fortinet for WECA + multi-site
Bristol multi-site customers (WECA estate, multi-branch retail, BCC) consolidating ageing Cisco onto Fortinet single-pane — driven by SD-WAN refresh and TCO pressure.
On-prem → AWS / Azure UK
Bristol fintech and aerospace customers lift-and-shifting from South West DC footprint to AWS eu-west-2 or Azure UK-South — FCA-aware for fintech, MOD-aware for aerospace.
Exchange-on-prem → M365 for WECA + universities
Frequent second-wave for Bristol public-sector — Exchange-on-prem to M365 GCC, on-prem PBX to Teams Voice, integrated with the customer's existing identity stack.
What a Servnet Bristol 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 Temple Quarter fintech and Filton aerospace, 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.
Bristol migration engagements we run
- ▸Temple Quarter fintech off VMware to NutanixBS1 / BS2 fintech with 150–500 VMs moving from vSphere to Nutanix AHV — typically 10–14 weeks discovery-to-decom.
- ▸WECA Cisco → Fortinet multi-siteWECA estate + BCC multi-site Cisco ASA + Meraki consolidating onto FortiGate + FortiSwitch.
- ▸Bristol fintech on-prem → AWSTemple Quarter scale-ups moving South West DC footprint to AWS eu-west-2 — with FCA outsourcing-materiality memo prepared.
- ▸NHS BNSSG to Crown Hosting / AzureBNSSG-affiliated trusts migrating off ageing on-prem to Crown Hosting or Azure UK-South — DSP Toolkit + HSCN retained.
- ▸Filton aerospace HCI consolidationAirbus / BAE / Rolls-Royce supply customers consolidating multi-site IT onto Nutanix or vSAN — MOD-aware, NCSC-aligned.
- ▸Universities to M365 + AzureBristol + UWE migrating Exchange-on-prem + on-prem file servers to M365 + SharePoint + OneDrive.
How a Bristol migration runs week-by-week
Weeks 1–2 — discovery + estate map
Automated discovery + interviews with application owners. Produces migration BoQ and risk register.
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 wave.
Weeks 9–10 — soak + decom
New platform runs clean for soak. Once signed off, decommission begins.
Bristol vendor migrations — common questions
We're a Bristol fintech with 200 VMs on vSphere — Broadcom has tripled. What's right?
For most Temple Quarter fintech with that footprint, Nutanix AHV (regulated-friendly, predictable per-node pricing). 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 Temple Quarter trading?
Yes — point of parallel-run. Build the new platform alongside the old, migrate trading-critical systems last, validate during pre-open hours, only cut over once your team signs off.
How do you handle FCA outsourcing materiality for a Bristol cloud migration?
For FCA customers we produce technical input — which IBS touch the migrated platform, destination region resilience, exit plan. Your compliance team writes the final memo.
Can you do Cisco → Fortinet across WECA + 3 councils 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 Bristol?
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 Filton aerospace supplier with inherited multi-site IT — can you consolidate?
Yes — frequent engagement for aerospace-supply customers. Discovery across estates, target design (typically Nutanix HCI), consolidated migration with NCSC-aligned baseline.
