Vendor migrations in Sheffield —
VMware, Cisco, on-prem to cloud, done safely.
Servnet runs parallel-run vendor migrations for Sheffield businesses facing Broadcom-era VMware pricing, Cisco end-of-life, on-prem to cloud consolidation. Discovery → pilot → migration waves → decommission. Sheffield cutovers happen Friday-evening to Sunday so Monday open is clean across NHS SY, Irwin Mitchell, AMRC supply and the SYCA estate.
Why Sheffield is in the middle of every current migration cycle
Sheffield concentrates firms feeling current migration triggers — VMware Broadcom on NHS SY + Irwin Mitchell estates, Cisco EOL across multi-site SYCA networks, AMRC research compute modernisation.
VMware → Nutanix for Sheffield regulated estates
Broadcom's pricing is forcing the question on NHS SY trusts + Irwin Mitchell HQ. VMware → Nutanix AHV most common destination.
Cisco → Fortinet for SYCA + multi-site
Sheffield multi-site customers (SYCA, 3 SY authorities, multi-branch retail, multi-site NHS) consolidating ageing Cisco onto Fortinet.
On-prem → AWS / Azure UK
AMRC research compute, Sheffield tech and Irwin Mitchell-class firms lift-and-shifting from Sheffield DC footprint to cloud.
Steel industry IT consolidation
Sheffield steel customers consolidating multi-site IT (often inherited through acquisitions) onto a single HCI platform with IT/OT segregation retained.

New platform runs clean for soak.
Sheffield vendor migrations — common questions
We're a Sheffield firm with 200 VMs on vSphere — Broadcom has tripled. What's right?
For most Sheffield firms with that footprint, Nutanix AHV or vSAN ESA. Model 3-year TCO including migration cost.
Can you migrate an NHS SY trust to Azure without HSCN breakage?
Yes — frequent NHS engagement. We retain HSCN connectivity throughout the migration.
How do you handle AMRC research compute migration without breaking ongoing experiments?
For AMRC and university research customers we plan migrations around experiment schedules — typically researchers given advance notice of windows, with rollback capability for critical experiments.
Can you do Cisco → Fortinet across SYCA + 3 SY authorities with no downtime?
In most cases yes — install Fortinet in parallel, migrate sites one at a time.
How long does 200-VM VMware → Nutanix take in Sheffield?
Discovery → final-VM-on-new-platform is typically 10–14 weeks.
We're a Sheffield steel customer with inherited multi-site IT — can you consolidate?
Yes — frequent engagement for steel + manufacturing customers post-acquisition. Discovery across estates, target design (typically Nutanix HCI with IT/OT segregation retained).
