Migrating off VMware to open source: a hands-on workshop

No theory for theory's sake: at the workshop you migrate a real virtual machine off VMware with your own hands, in a live environment — and leave with a step-by-step migration plan.

  • Free with registration
  • Seats are limited
  • Held in Russian

What is happening to VMware

After Broadcom bought VMware, the familiar model ended: perpetual licenses are no longer sold, only subscriptions remain, and renewal bills have grown severalfold — not by percentages, but by multiples. Support for vSphere 7 ended in the autumn of 2025, so "leaving everything as is" stopped being a free option too.

Meanwhile, your infrastructure works, your team knows it, and nobody wants to break it. The real question sounds different: what can replace VMware without losing your data, your people, or your control — and without ending up dependent on the next vendor.

Where to migrate: meet Cozystack

Cozystack is an open virtualization platform built as a VMware replacement: virtual machines, networking, storage, monitoring, and backups in one system. The platform is free, its code is open, and the project grows within the CNCF — the same foundation that stewards Kubernetes.

You don't have to take this on faith: the entire workshop runs inside Cozystack. You will work with the platform hands-on and decide for yourself whether it fits.

  • Virtual machines
  • Networking
  • Storage
  • Monitoring
  • Backups

What you will do

No three-hour slide decks. Every participant gets a personal working environment on a real cluster, and that is where you spend almost all of the time.

00:00

How we got here

talk

What happened to VMware's prices and support — and what it means for your infrastructure. The only slide block of the day.

00:15

Meeting the platform

hands-on

You open your personal working environment and find everything familiar in it: storage, networking, live migration, monitoring.

00:40

Migrating a virtual machine

hands-on

You export a machine straight from a running VMware server, convert it, and start it on the new platform. It answers requests — your first migrated VM.

01:30

Building the infrastructure around it

hands-on

A database in a couple of minutes, a service published to the network, monitoring and backups. At the end, the whole setup comes back up from a single file.

02:20

An honest conversation about limitations

discussion

What will not move one-to-one, and who should not migrate. Tell us about your hardest machine — and get a straight answer.

02:40

A migration plan for your infrastructure

talk

Where to start at home: the first non-critical workload, the stages of the move, and the support you get after the workshop.

What you leave with

01

A virtual machine you migrated yourself — the first practical step of your migration.

02

A step-by-step plan: where to start, what to move first, and how to split the move into stages.

03

Clarity about VMware: what will migrate, what won't, and when staying is the wiser choice.

04

Working skills with an open virtualization platform — without courses or months of self-study.

05

Materials and cheat sheets to work with at home — plus a month of support after the workshop.

Who should come

VMware administrator / sysadmin

  • Everything is explained through concepts you already know — no Kubernetes required.
  • You migrate a machine yourself and take the working cheat sheet home.
  • A test environment and a maintainer chat for another month afterwards.

Infrastructure lead

  • The full migration picture, including the limitations — we state them first.
  • A pilot plan tied to your renewal date.
  • Come together with one of your engineers: one sees the "how", the other decides the "when".

Technology executive

  • The economics of the move, without marketing promises.
  • Straight answers about risk: open code, independent support, no single-vendor dependency.
  • A trained engineer and an honest assessment of your hardest systems — the same day.

DevOps engineer

  • Virtual machines and containers in one system, managed as code.
  • Databases, storage, and monitoring — built in, no manual assembly.
  • A platform you and the virtualization team can finally agree on.

A month of support and learning after the workshop

  • Your test environment stays with you for another 30 days — for experiments and certification prep.
  • Take-home lab exercises — with support from the Cozystack maintainers.
  • A chat where Cozystack maintainers answer your questions.
  • The opportunity to earn the Cozystack Certified Fundamentals certificate — free.

Cozystack maintainer · Aenix co-founder

Timur is a maintainer of the open Cozystack platform and a co-founder of Aenix, the company behind it. The workshop format is his: no marketing slides, most of the time at the terminal, and the platform's weak points named before its strong ones.

About the workshop

This is a free hands-on workshop for people who run VMware and are deciding what to do next. It takes place in Tashkent, Bishkek, Almaty, and Astana. In one day, participants migrate a real virtual machine off a running VMware server onto Cozystack — an open virtualization platform developed within the CNCF — with their own hands. Most of the time is practice in a personal working environment: migrating the machine, adding a database, monitoring, and backups. The workshop is led by Timur Tukaev, Cozystack maintainer and Aenix co-founder. Afterwards, every participant keeps a test environment for 30 days, a chat with the platform’s maintainers, take-home lab exercises, and the opportunity to earn the Cozystack Certified Fundamentals certificate. Attendance is free with registration; seats are limited.

Frequently asked questions

How much does it cost?

Attendance is free; you only need to register. Seats are limited — we want everyone to get real time at the terminal and an assistant’s attention when needed.

I run VMware but don't know Kubernetes. Will I keep up?

Yes. The workshop is built for exactly your profile: everything is explained through VMware concepts you already know, and assistants are there whenever something doesn’t work. Your experience is the foundation we build on.

What language is the workshop in?

Russian. Commands and materials are in English. This page also has a Russian version.

What should I bring?

A laptop with a browser — that’s all. Your working environment is prepared in advance; there is nothing to install.

Is this a sales presentation?

No. It is training: you spend most of the time working with your hands, and the program includes an honest conversation about what the platform cannot do and who should not migrate. No contracts, no pressure.

What exactly will I do with my own hands?

Move a virtual machine off a running VMware server, deploy a database, publish a service to the network, see how monitoring and backups work — and, at the end, bring the whole setup back up from a single file.

What happens after the workshop?

Your test environment stays with you for another 30 days, you receive take-home lab exercises, and you join a chat where Cozystack maintainers answer questions. Completing the labs earns you the Cozystack Certified Fundamentals certificate — also free.

We run Oracle, SAP, or specially licensed Windows. Will it migrate?

Maybe not — and we will say so directly. Vendor licensing restrictions are one of the topics of the honest-limitations conversation. Bring your hardest case and get a straight answer.

Can I bring my manager or a colleague?

Please do. The workshop works best in pairs — an engineer plus a manager: one leaves with hands-on experience, the other with a plan.

Can you send an official invitation letter for my employer?

Yes. On request after registration, we will send an invitation letter addressed to your company — justifying a day out of the office becomes easy.
