Natural candidate
Standardised workloads
Supported Linux or Windows VMs, known dependencies, reproducible networking and measurable availability objectives.
VMware Exit
Plan your VMware Exit
to Proxmox VE
Decide on evidence: inventory, compatibility, POC, target architecture, migration waves and documented rollback.
Authorisation criteria
Five GO/NO-GO decisions before VMware decommissioning
These criteria come before the schedule and any cutover promise. Each gate produces verifiable evidence. If a criterion fails, the wave does not start: the scenario is corrected, postponed or excluded.
- 01
Qualified scope
Inventory, criticality, dependencies, change windows and application owners are validated.
- 02
Target demonstrated
The POC measures performance, network, storage, backup, HA and operations on representative workloads.
- 03
Reversible pilot
A first non-critical wave validates the procedure, application checks and rollback.
- 04
Waves authorised
Each batch has a runbook, owner, stop criteria and proof of restorable backup.
- 05
VMware Exit
Decommissioning after stabilisation, documentation, knowledge transfer and business approval.
Decommissioning rule
The VMware source remains available until the target is stable, restores are validated, technical and application owners approve, runbooks are handed over and the business owner gives formal acceptance.
Why migrate now?
A VMware Exit is more than a hypervisor swap. It must make the economic case, technical constraints and the team's ability to operate the target explicit.
Broadcom renewals and budget predictability to reassess
Strong dependency on the VMware/Broadcom ecosystem
Broader VCF scope: integrated vSphere, vSAN, NSX and operations
Potential gap between the proposed VCF scope and actual requirements
Operational risk during renewals and migrations
Need to simplify operations and reduce lock-in
Is Proxmox the right target for your entire estate?
Not always. A credible VMware Exit starts by segmenting the estate: what can move, what requires a POC and what should temporarily remain on VMware or use another target.
Prove in a POC
Sensitive workloads
Low-latency databases, appliances, application-aware backup, HA, replication or vSAN/NSX dependencies require representative tests.
Decision required
Vendor constraints
Certification, an unsupported appliance or a contract requiring vSphere may justify a hybrid path or a documented exception.
Our migration approach
STEP 01
Inventory & analysis
Precise mapping: VM list, CPU/RAM/storage consumption, network dependencies, critical applications identified.
STEP 02
Target Proxmox architecture
Design of the target architecture based on production constraints and continuity objectives: network segmentation and resilience, high availability strategy, storage architecture and sizing adapted to real workloads — not a generic template.
STEP 03
Wave migration
VM prioritization: non-critical first, critical last with parallel VMware production maintained.
STEP 04
Validation & switchover
Exhaustive application tests, SLA validation, controlled switchover, VMware decommissioning after stabilization.
Deliverables that make the plan executable
You leave with operational material for architecture, operations, security, procurement and application owners — not a generic recommendation.
- Estate map and compatibility matrix
- Target architecture and sizing assumptions
- POC report with GO/NO-GO criteria
- Migration wave plan and change calendar
- Migration, validation and rollback runbooks
- Operations, backup, monitoring and handover model
Frequently asked questions
How long does a migration take?
It depends on the scope, production constraints, application dependencies and available migration windows. Some migrations are done in progressive waves over several months to minimize operational risk.
Can we roll back if a wave fails?
Each wave has a defined rollback path, tested where the workload allows it. The VMware source is retired only after technical, application and business validation.
Do we need to replace servers?
Not necessarily. Proxmox VE runs on standard x86 hardware. We assess whether existing hardware is compatible and sufficient.
Can your teams maintain Proxmox alone after migration?
That's our goal. We provide runbooks, operational documentation and train your system administrators.
Does Proxmox always replace vSAN and NSX directly?
No. vSAN and NSX capabilities must be separated by use case: distributed storage, micro-segmentation, routing, automation and observability. The POC validates useful equivalents and documents functions that require another component or a hybrid path.
How do we secure backup, disaster recovery and support after the VMware Exit?
The target includes a tested backup strategy, RPO/RTO objectives, recovery scenarios and an explicit support model. These are GO/NO-GO criteria, not tasks postponed until after cutover.
