What this case study covers

Broadcom's 2024 licensing changes ended the VMware VCSP program and made per-core subscription pricing untenable for most managed service providers. This case study documents exactly what one MSP did about it: a full migration from a 40-host VMware cluster to Proxmox VE, completed without customer-visible disruption.

It covers the commercial decision, the technical execution, and the commercial outcome — including how the MSP restructured their service offering around Proxmox and launched a new cloud tier within 90 days of project completion.

1

The business case

How the MSP modelled the cost delta between staying on VMware VCSP and migrating to Proxmox — including hardware, licensing, internal time, and customer risk. The numbers that forced the decision.

2

Environment assessment & planning

A 40-host cluster with 400+ VMs, complex SDN, and customer workloads across multiple tenants. How the environment was assessed, workloads classified, and a migration sequence designed around operational risk.

3

Proxmox VE cluster design

The target architecture: cluster topology, Ceph storage design, SDN and VLAN structure, Proxmox Backup Server layout, and HA configuration. The design decisions and why they were made.

4

Migration execution

The actual migration: tooling choices per workload type, how cutover windows were structured to minimise customer impact, what went wrong and how it was handled, and the final rollout schedule.

5

Commercial outcome & new service launch

The final infrastructure cost, customer retention through the migration, and how the MSP launched a Proxmox-based cloud offering — with pricing models, service tiers, and onboarding processes — within 90 days.
