Seamlessly Migrate.
Securely Scale.

VMCatalyst is the orchestration layer for effortless VMware-to-KVM migration, giving enterprises an automated path to a modern infrastructure.

VMware estate in place Running on open infrastructure

Everything a migration needs, in one control plane.

Discovery, conversion, sync and cutover run as one orchestrated workflow — so a migration stops being a project and becomes an operation.

Automated orchestration

Scan the estate, group workloads into waves, and let the scheduler drive every conversion in dependency order. No runbooks to babysit.

Zero-downtime live-sync

Changed blocks replicate continuously while the source keeps serving traffic. Cutover is a switch, measured in seconds, not a maintenance weekend.

Learn more

Vendor-agnostic freedom

One pipeline targets Proxmox VE, plain KVM and OpenStack. Pick the destination on price and fit, and change your mind later without redoing the work.

Learn more

Safety-net rollback

The source VM stays intact and bootable until you sign off. If validation fails, one command returns the workload to where it started.

The Blueprint

Five phases, one agentless control plane, and no lock-in at either end. Here is what runs underneath.

  1. Phase 1

    Discover

    Read-only inventory of hosts, VMs, networks and dependencies through vCenter.

  2. Phase 2

    Plan

    Group workloads into waves, map networks and storage, flag blockers before you commit.

  3. Phase 3

    Replicate

    Disks convert to QCOW2 or raw while change-block tracking keeps the copy current.

  4. Phase 4

    Cut over

    Freeze, flush the final delta, boot on the target, and move the address.

  5. Phase 5

    Verify

    Automated boot, service and network checks. Sign off, or roll back untouched.

Priced per migrated VM. Nothing else.

No host counts, no core counts, no renewal cliff. You pay when a workload lands and passes verification.

“We had budgeted eleven months and a licensing renewal we did not want to sign. VMCatalyst moved 2,400 VMs to Proxmox in fourteen weeks, and nobody outside the platform team noticed.”
