For a 1,000-user organization we moved the core estate from VMware to Proxmox VE backed by Ceph — a confidential engagement. That included server workloads and, as one stream of the same program, desktop delivery that stayed on Omnissa VDI while the hypervisor underneath changed. Custom migration and guest prep tooling carried the waves.
Infrastructure
Full architectural transition: ESXi cluster teardown, VirtIO injection, Ceph-backed HCI, and a sequenced, wave-based cutover designed to keep disruption bounded and reversible.
Also in scope: end user
Part of the estate ran Omnissa VDI. Those desktops were not a separate project — they moved with the platform. Omnissa stayed as the desktop layer; Proxmox and Ceph became the compute and storage underneath.
