Why Southampton is in the middle of every current migration cycle
Southampton concentrates firms feeling current migration triggers — VMware Broadcom on NHS HIOW + Carnival UK + BAE-supplier estates, Cisco EOL across multi-site Hampshire networks, port operational modernisation, NHS HIOW cloud-shift.
VMware → Nutanix for Southampton regulated estates
Broadcom's pricing is forcing the question on NHS HIOW + BAE-supplier customers. VMware → Nutanix AHV most common.
Port operational system modernisation
DP World Southampton + ABP Southampton modernising port operational systems with cloud-bridge designs.
Cisco → Fortinet for Hampshire multi-site
Hampshire multi-site customers consolidating ageing Cisco onto Fortinet single-pane.
Exchange-on-prem → M365 for SCC + universities
Frequent second-wave for Southampton public-sector and universities.

Southampton vendor migrations — common questions
We're a Southampton firm with 150 VMs on vSphere — Broadcom has tripled. What's right?
For most Southampton firms with that footprint, Nutanix AHV or vSAN ESA. Model 3-year TCO including migration cost.
Can you migrate an NHS HIOW trust to Azure without HSCN breakage?
Yes — frequent NHS engagement. We retain HSCN connectivity throughout.
Can you modernise port operational systems without disrupting 24×7 operations?
Yes — for port + maritime customers we plan migrations around tight operational windows with extensive parallel-run + rollback capability.
Can you do Cisco → Fortinet across Hampshire CC + 11 districts?
In most cases yes — install Fortinet in parallel, migrate sites one at a time.
How long does 150-VM VMware → Nutanix take in Southampton?
Discovery → final-VM-on-new-platform is typically 10–14 weeks.
We're a BAE Systems Southampton supplier wanting to consolidate multi-site IT?
Yes — frequent engagement for defence supplier-chain. NCSC-aligned consolidation with IT/OT segmentation retained.
