PROXMOX IN ENTERPRISE ENVIRONMENTS

From VMware
to Proxmox.

A plan that works with your renewal deadline.

We plan and deliver your VMware exit. With your IT team, we establish what can be migrated before the next renewal, what it will cost and which applications and connected systems need adapting. Existing hardware is part of the target architecture.

COSTS AND TIMELINE

What is achievable
before the contract ends?

An expensive renewal offer creates pressure. We first check deadlines, dependencies and available capacity. You learn whether a complete migration is realistic or a temporary arrangement is needed.

01

Applications and dependencies

We assess systems, interfaces and vendor support. Backup, networking, permissions and exceptions such as encrypted VMs are part of the assessment.

02

Target architecture and operations

We size clusters, storage and networking. Availability, recovery, monitoring and operational ownership help determine the design.

03

Costs and contract terms

We compare continuing operations with migration, including hardware, subscriptions, implementation and connected systems. Notice periods, remaining contract terms and parallel running shape the timeline.

THE OUTCOME

A target architecture, cost assessment and deliverable migration plan with explicit prerequisites. This allows IT and management to decide on the next step.

Initial assessment checklist
  • Contract end date, notice period and renewal offer
  • Host and VM counts, storage design and available capacity
  • Critical applications, vendor support and connected systems
  • Backup, recovery objectives and acceptable interruptions
  • Availability of your IT team and participating providers

This information helps define the assessment scope. A reliable effort estimate follows the technical analysis.

USE EXISTING INVESTMENTS

Replace VMware.
Not necessarily the hardware.

We also deliver migrations on suitable existing hardware. We assess technical and commercial suitability based on specifications, remaining service life, support and capacity during migration.

EXISTING HYPERCONVERGED INFRASTRUCTURE

Reuse servers from a vSAN cluster.

After assessment, the servers may be suitable for the new platform. vSAN itself is not retained. We assess hardware and capacity and plan a new storage design, including data transfer.

EXISTING EXTERNAL STORAGE

Integrate existing SAN systems.

A suitable SAN can continue serving the new platform. Connectivity, storage methods and backup are checked for the specific combination. VMware datastores are not retained unchanged.

NO ASSUMPTION OF A COMPLETE SECOND ESTATE

We compare conversion of existing infrastructure with temporary capacity and a parallel new build. Total cost, possible interruptions and a realistic deadline determine the choice.

APPLICATIONS AND CONNECTED SYSTEMS

What depends
on VMware today?

The hypervisor is only part of the change. We establish required vendor approvals and adaptations early, coordinating the work with your application and operational partners.

APPLICATIONS

Clarify support and exceptions.

We check support requirements, virtual appliances, guest operating systems and licence dependencies. Systems without confirmed support need agreed testing or a separate transition path.

NETWORKING

Resolve dependencies before migration.

We assess VLANs, routing, firewalls and, where relevant, vDS or NSX. EVPN, BGP and site connectivity are planned to fit the target environment.

OPERATIONAL TOOLS

Adapt backup and tools.

We check product versions, licences and recovery procedures. Monitoring, provisioning and scripts integrated with vCenter are adapted or replaced. New procedures are tested before handover.

Our enterprise platform experience
INFORMATION SECURITY & COMPLIANCE

Translate requirements
into implementation.

Especially in regulated environments, it must be clear which requirements the new platform meets. We coordinate technical measures with your IT team, information security and relevant assurance teams.

REQUIREMENT

What must be met?

Record protection needs, access rules, recovery objectives and internal requirements. Define owners and acceptance criteria.

TECHNICAL IMPLEMENTATION

How will it be achieved?

Design and implement permissions, network separation, logging and backup in the target environment.

TESTING & EVIDENCE

How will we demonstrate it?

Run tests, document results and present open issues for decision. This creates usable operational documentation.

Sysfacts is responsible for the agreed technical implementation and documentation. Business approvals and assessment of regulatory obligations remain with the responsible parties.

IMPLEMENTATION

Turn the plan
into a running platform.

Your applications determine the sequence. We prepare the target environment and agree tests, maintenance windows and approvals with the responsible teams.

  1. 01

    Build the target environment

    Configure clusters, networking and storage. Integrate backup and monitoring. Document configurations and access.

  2. 02

    Run a pilot and tests

    Transfer representative systems, check applications with their owners and test recovery.

  3. 03

    Migrate in agreed waves

    Group systems by dependency. During the cutover window, we focus on the systems being transferred.

  4. 04

    Accept and support

    Review results together, hand over documentation and monitor operations during the agreed hypercare period.

PROJECT EXPERIENCE · WISMAR UNIVERSITY

One central
data centre.

Around 500 virtual machines on ten nodes across two fire compartments. We consolidated requirements, supported implementation and helped the data centre team with failure testing and acceptance.

The case shows our work on a Proxmox target architecture with separate environments for three faculties.

BEFORE YOU START

What clients
want to know.

A useful migration plan also identifies limitations. We clarify these questions before you commission implementation.

Do all systems have to move at once?

No. We plan migration waves based on dependencies. Temporary parallel operation may be useful. Licence costs, interfaces and eventual decommissioning belong in the plan.

What if some applications cannot move yet?

We identify those systems and assess a transition path with their vendors. A temporary remaining VMware environment may be necessary. Its licence costs, duration and later replacement are explicitly planned.

How much downtime should we expect?

That depends on the applications and transfer method. We test representative systems and use the results to define the windows. A blanket promise without assessment would not be reliable.

Can we commission only the assessment first?

Yes. Assessment and implementation can be commissioned separately. We define the scope in advance. You can use the documented results without a follow-on engagement.

YOUR PROJECT

When does your
VMware contract end?

Tell us the contract end date, approximate scale and existing hardware. We discuss the main dependencies and establish how to approach assessment and implementation.
