A vCenter alternative: managing and migrating Proxmox after VMware
Leaving VMware means leaving vCenter. How to manage your virtualization without it, and migrate your VMs from ESXi to Proxmox with the native import wizard. No jargon.
Leaving VMware raises two very concrete fears. First: how do I manage my servers without vCenter? Second: how do I move my virtual machines off ESXi? Good news: in 2026, both have a clear answer on the Proxmox side.
What vCenter is actually for
vCenter Server is VMware’s central console: it aggregates the inventory of your ESXi hosts, live migration (vMotion), high availability and load balancing. It is powerful, but it is also a separate appliance that must be licensed, on top of the hosts.
When you look at what you actually need day to day, the list is shorter: see and operate your VMs, open a console, move a machine without shutting it down, and restart automatically after a failure. All of that exists in Proxmox, with no separate management server.
Management: the Proxmox interface and Datacenter Manager
Every Proxmox VE cluster ships with its own web interface. There is no “vCenter” to install and license alongside: management is native to the cluster. You create, clone, start, migrate and back up your machines there, with the built-in console.
For those who run several clusters or several sites (vCenter’s true multi-datacenter use case), Proxmox recently introduced the Proxmox Datacenter Manager. Open source, stable since late 2025, it gives a centralized view of all your nodes and clusters, and lets you migrate a VM from one cluster to another without manual network reconfiguration. The fundamental difference from vCenter: it is free and adds no licensing cost.
What vCenter did, and the Proxmox equivalent
| VMware function | Proxmox equivalent |
|---|---|
| vCenter console (inventory, access) | Web interface built into the cluster |
| vMotion (live migration) | Live migration, included |
| High availability (HA) | HA built into the cluster |
| Multi-site management | Proxmox Datacenter Manager (free) |
| vSAN (storage) | Ceph and ZFS, included |
| Backup (Veeam) | Proxmox Backup Server, included and immutable |
Most of vCenter’s day-to-day needs have a Proxmox equivalent with no extra licensing cost. The notable gaps (fully automatic load balancing, advanced software-defined networking) mostly concern very large estates, and can be handled through configuration.
Migration: the native ESXi import wizard
This is the part that reassures people most. Since Proxmox VE 8, an import wizard is built right into the interface. The idea:
- In Proxmox, you add your ESXi host as storage (address, username, password).
- You browse the VMs on the ESXi host from the Proxmox interface.
- A right-click, “Import”, and Proxmox pulls the machine and converts its disks on the fly to its own format.
Import has been tested with ESXi 6.5 through 8.0. A few limits to know: the VM must be powered off during the import (a short interruption), snapshots slow the operation down, and encrypted, vSAN-backed or vTPM disks are not supported through this path. For those cases, there is still the OVF/OVA file import or manual disk migration.
In practice, how a migration unfolds
A good migration is not done in one shot. You proceed in waves:
- You stand up the target Proxmox cluster and validate networking and storage.
- You first import non-critical machines, to break in the process.
- You reboot and test each imported VM before putting it into service. This is the right moment to adopt a backup verified by real restore.
- You keep VMware running until full validation, then switch over.

What if you would rather not manage all this yourself
Migrating and operating Proxmox takes time and skills. You can also hand us the platform: at Rēzau, your private cloud runs on Proxmox, operated by our team, hosted in Canada. And if you prefer to keep your servers on-site, our consulting and migration service guides you from strategy to cutover, with no downtime.
Frequently asked questions
Do I need a separate management server, like vCenter, with Proxmox? Not for a single cluster: the interface is built in. To drive several clusters, the Proxmox Datacenter Manager does it, for free.
Can I migrate a VM without reinstalling it? Yes. The import wizard pulls the existing machine from ESXi and converts its disks. There is no reinstall.
Does migration cause downtime? A short one, yes: the VM must be powered off during the import. You organize it in waves, outside peak hours, to keep it to a minimum.
Does Proxmox handle live migration, like vMotion? Yes. Once your machines are on Proxmox, live migration between nodes is included, with no extra license.
