Broadcom‘s 2023 acquisition of VMware triggered a hypervisor migration wave that is accelerating, not settling — and the technical risks of moving workloads to competing platforms remain widely underestimated, according to the announcement.
Gartner research VP Julia Palmer recently predicted VMware would lose 35% of its workloads by 2028. Price increases, licensing restructures and eroded support have pushed customers toward alternatives including Microsoft Hyper-V, Azure Stack HCI, Nutanix AHV, Proxmox VE and KVM. A 2025 incident in which VMware Workstation auto-updates broke due to a Broadcom URL redirect added operational grievances to financial ones.
The migration path, however, is not clean.
Why the technical risk is higher than it looks
Hypervisors do not interoperate. Disk formats, hardware abstractions, driver stacks and networking models differ between platforms. Virtual hardware versions, storage controllers, chipset emulation and network virtualization layers do not translate cleanly across environments. Snapshot and template behavior varies. Configuration gaps that appear minor during testing can produce instability only visible once workloads face real production pressure.
The standard mental model — export, convert, import — understates how many variables can fail in sequence.
Even carefully planned migrations routinely exceed maintenance windows. When a window closes with systems still unstable, the consequences include missed transactions, stalled operations and SLA violations. The announcement recommends teams plan for worst-case downtime scenarios rather than ideal ones, and establish in advance who holds go/no-go authority, how long each workload can realistically stay offline, and what the communication plan looks like if restoration runs long.

Backup as the non-negotiable prerequisite
The report frames verified, restorable backup — not a conversion tool — as the single most important prerequisite for any hypervisor migration. Full-image, application-consistent backups that can restore to dissimilar hardware or an entirely different virtualization platform are described as essential, not optional.
Recovery drills, the announcement says, should happen before migration begins, not after cutover.
A platform-agnostic backup architecture serves two purposes: it provides a restoration path from source to destination, and it allows rapid reversion to the original platform if compatibility or performance problems emerge post-migration. So-called any-to-any recovery — the ability to restore from physical, virtual or cloud environments to any other destination — reduces both migration risk and long-term vendor dependency.
Migration also creates what the report calls a “dangerous gray zone” for backup and disaster recovery, where environments are split across old and new platforms simultaneously. That period, the announcement warns, is precisely when recoverability gaps are most likely and most damaging. Maintaining consistent protection across both environments during transition is described as a distinct operational requirement, not something that resolves itself once cutover completes.
The piece was sponsored by Acronis, which markets Acronis Cyber Protect as a platform it says cuts migration time by up to 60%. The underlying technical guidance, however, applies regardless of tooling: organizations that migrate without tested, platform-independent backup coverage are accepting risks that may not surface until the migration is already in crisis.
