Proxmox Virtual Environment deployment
We deploy Proxmox Virtual Environment for server virtualisation and migrate virtual machines from VMware and Hyper-V, as an authorised Proxmox partner based in Lublin, Poland. Backups run on Proxmox Backup Server, and Proxmox Mail Gateway protects your email. We supply subscriptions and maintain the environment after deployment.
Why companies move to Proxmox
-
VMware licences have become more expensive
After Broadcom acquired VMware, many companies received higher bills and new licensing terms. Proxmox Virtual Environment is open-source software: you pay only for the support subscription.
-
An old Hyper-V server needs replacing
Replacing a server is a good moment to review virtualisation. The virtual machines can move to Proxmox in the same project.
-
One server is a single point of failure
When the server fails, the whole company stops. In a Proxmox high-availability cluster, virtual machines restart on another node.
-
VM backups keep taking more space
Proxmox Backup Server makes incremental, deduplicated backups, so each new copy takes less space and a single file can be restored without restoring the whole machine.
Proxmox subscriptions: Basic, Standard and Premium
Every paid subscription gives access to the stable Enterprise Repository with tested updates and security patches, and to the vendor’s technical support. The levels differ in the number of support tickets and response times:
| Level | Proxmox Virtual Environment | Proxmox Backup Server | Proxmox Mail Gateway |
|---|---|---|---|
| Basic | 3 tickets a year, response within 1 business day | 5 tickets a year, response within 1 business day | 5 tickets a year, response within 1 business day |
| Standard | 10 tickets a year, response within 4 hours, remote support | 15 tickets a year, response within 4 hours, remote support | 15 tickets a year, response within 4 hours, remote support |
| Premium | unlimited tickets, response within 2 hours, remote support | unlimited tickets, response within 2 hours, remote support | unlimited tickets, response within 2 hours, remote support |
Response times apply to critical tickets submitted through the Proxmox customer portal. Subscriptions are billed annually: Proxmox Virtual Environment per physical CPU, Proxmox Backup Server per server and Proxmox Mail Gateway per host. The vendor also offers a Community subscription with access to updates but without support tickets. This overview reflects the vendor’s terms as of 8 November 2026. Current terms are on proxmox.com.
With a Premium subscription for Proxmox Virtual Environment, the vendor also provides round-the-clock support. This support is not part of our service.
We add our own support to the vendor’s. Under our standard SLA, we respond within 2 business hours. You submit tickets to Proxmox as the subscription owner, and we help you prepare them, including collecting diagnostic data.

Proxmox Server Solutions and the subscription model
Proxmox Virtual Environment has been developed since 2005 by the Austrian company Proxmox Server Solutions. The platform’s code is open, and the company earns its revenue from subscriptions and training. Open code means your environment does not depend on a single vendor. The platform runs on standard x86 servers, including older ones, so changing virtualisation often does not require new hardware.
You can read more about the platform on the vendor’s website, proxmox.com. If you want us to look after your servers and the rest of your infrastructure after deployment, see server and network administration.
CONETSO GROUP Sp. z o.o. is an official reseller partner of Proxmox Server Solutions.

Proxmox Virtual Environment: virtualisation without licence fees
Proxmox Virtual Environment is an open-source server virtualisation platform. It runs virtual machines (KVM) and lightweight containers (LXC) on one system, all managed from a web interface. It has built-in clustering with high availability and live migration. It supports local storage (ZFS, LVM), shared storage (NFS, iSCSI) and distributed storage (Ceph), as well as software-defined networking and a firewall.
- Virtual machines and containers on one platform
- High-availability cluster with live migration
- Web-based management
Migration from VMware and Hyper-V
We start with an inventory of virtual machines, their dependencies and maintenance windows. Proxmox has a built-in tool for importing machines from VMware ESXi, and Hyper-V machines move by converting their disks. Less critical systems go first and are checked before we move the servers your business depends on. A rollback plan is in place throughout.
- Inventory of machines and dependencies before migration
- Migration in stages, starting with less critical systems
- Rollback plan at every stage
Proxmox Backup Server: incremental, deduplicated backups
Proxmox Backup Server is open-source software for backing up virtual machines, containers and physical servers. Backups are incremental and deduplicated, so they take less space, and you can restore a whole machine or a single file. Backups can be synchronised to a second server at another site. If you already use Veeam (we are a Veeam partner too), we back up Proxmox with Veeam.
- Virtual machines, containers and physical servers
- Backup synchronisation to a second site
Proxmox Mail Gateway: email protection
Proxmox Mail Gateway is open-source software that sits in front of your mail server and checks every message before it reaches a mailbox. It stops spam, viruses and dangerous attachments, and puts suspicious messages into quarantine, from which a user or an administrator can release them. Filtering rules can be set for the whole company, for departments or for individual people. Proxmox Mail Gateway works with common mail servers.
- Protection against spam, viruses and ransomware
- Quarantine for suspicious messages and attachments
- Filtering rules for the company, departments and individuals
How we work

Frequently asked questions
Is Proxmox free?
The platform itself is open-source software under the AGPLv3 licence and requires no licence fees. The paid subscription gives access to the stable Enterprise Repository with tested updates and to the vendor's technical support. For production environments, we recommend a subscription.
Which subscription level should we choose?
Where downtime stops your business, we recommend at least Standard, which includes remote support from the vendor and a 4-hour response for critical tickets. Basic is enough for smaller environments, where we resolve most issues ourselves as part of our managed IT services. We choose the level with you after reviewing your environment.
Can you move virtual machines from VMware without downtime?
We keep downtime to agreed maintenance windows. Most machines are moved outside business hours, in stages, and each one is checked after the move. The switchover time depends on disk size and the migration method, so we state it in the migration plan.
Is Proxmox suitable for a small business?
Yes. Proxmox runs on a single server and can grow into a cluster as the business grows. A small business can keep its backups on Proxmox Backup Server.
Can we buy just the subscription?
Yes. As an authorised partner, we also supply Proxmox subscriptions to companies that administer their environment themselves. You then raise support tickets with the vendor yourself, and we can help you prepare them on request.
