Broadcom's licensing model has redefined the economics of VMware. We've migrated 30+ environments to Proxmox VE in the last 24 months — including ESXi clusters, Veeam backup chains, and NSX networking. Vendor-independent migration, planned in waves, reversible until cutover.
ESXi-import natively supported in Proxmox since 7.4.
Migration runs in waves — risk is bounded per wave.
Veeam replacement and NSX-equivalent included in scope.
CIO, Mid-Market Group, Manufacturing
A fixed, standardized path from discovery to strategy to implementation,followed by ongoing assurance operations. Standardized in method anddeliverables—scalable via scope, tiering, data volume, and service level.
How we migrate
We design Proxmox clusters around three proven architectures. Choose by recovery objectives, scale, and existing infrastructure.
PHASE 1 (1–2 weeks)
Migration Assessment.
Inventory, dependencies, sizing, business case, risk catalog.
Output: Migration plan + cost projection.
PHASE 2 (4–12 weeks)
Wave Execution.
Pilot, waves, cutover.
Reversible until decommission.
Rollback plan per wave.
Output: Live cluster, workloads migrated.
PHASE 3 (2–4 weeks)
Post-Migration Hardening.
HA validation, DR drill, runbook handover.
Optional transition into 24x7 Managed.
Output: Hardened cluster + handover.

“The combination of precise planning and consistent responsibility enabled us to make a risk-free transition without a fallback environment. Sysfacts proved that the right approach saves costs and ensures quality.”

For most workloads, yes. We use parallel-run patterns: the Proxmox cluster runs alongside ESXi, workloads cut over individually with a tested rollback path. True zero-downtime requires application-side cooperation; we plan that with your application owners during the assessment.
Existing Veeam restore points remain readable until your retention expires. We can run Veeam in parallel with PBS for the transition period. Long-term we usually replace Veeam with PBS — see the dedicated /backup page for the comparison.
Proxmox SDN with EVPN provides equivalent segmentation. We map your NSX policies to SDN zones during the assessment. See /sdn for details.
Yes — and we recommend it. Proxmox can boot ESXi VMs directly via the native importer, allowing wave-based migration with rollback at any time.
A Migration Assessment in 1–2 weeks gives you a migration plan with cost projection — defensible, dated, signed off.
