Broadcom’s acquisition of VMware in 2023 set off a wave of migrations that reveals no indicators of subsiding. However transferring from VMware to a different hypervisor might introduce vital technical and operational dangers.
IT groups should put together for challenges that aren’t at all times obvious at the beginning of a migration.
Worth hikes, licensing modifications and shifts in buyer assist have pushed VMware clients to search for options. Current operational issues haven’t helped.
Final yr, VMware Workstation auto-updates failed on account of a Broadcom URL redirect. In 2026, the migration continues. Gartner analysis VP Julia Palmer not too long ago predicted that VMware would lose 35% of its workloads by 2028.
A lot of these workloads will shift to platforms corresponding to Microsoft Hyper‑V, Azure Stack HCI, Nutanix AHV, Proxmox VE or KVM. Sadly, the journey comes with challenges. Switching hypervisors is a high-stakes infrastructure change.
IT professionals have to give attention to finishing a profitable migration with their knowledge intact and accessible.
Why hypervisor migration is technically dangerous
It sounds easy: Export knowledge, convert it to a brand new format after which import it into a brand new hypervisor. However that course of is way riskier than it sounds.
That’s as a result of hypervisors don’t interoperate. A number of technical variables enhance the danger of failed or unstable migrations. Hypervisors differ in disk codecs, {hardware} abstractions, driver stacks and networking fashions.
Digital {hardware} variations, storage controllers, chipset emulation and community virtualization layers don’t at all times translate cleanly.
Snapshots and templates behave otherwise. Even delicate configuration variations can create instability that solely surfaces as soon as workloads are beneath actual manufacturing strain.
Migrating from VMware can enhance price, threat and operational drag, whereas limiting strategic choices.
Acronis Cyber Defend provides IT leaders management with a versatile, AI‑powered cyber safety platform that cuts migration time by as much as 60% and retains the enterprise safe and responsive all through change.

Backup is important to a profitable hypervisor migration
An important prerequisite for any platform migration is just not a conversion device. It’s verified, restorable backup.
Organizations want to guard workloads with full-image, application-consistent backups that IT professionals can restore not solely to the identical hypervisor however to dissimilar {hardware} or a wholly totally different virtualization platform.
IT groups have to carry out restoration drills earlier than they begin migration, not simply after cutover.
A platform-agnostic backup structure supplies a needed security internet. It permits restoration from the supply surroundings to the vacation spot surroundings, and it permits speedy reversion to the unique platform if compatibility or efficiency points come up.
The underside line is that knowledge stays secure and accessible.
Any-to-any hypervisor restoration — restoration from bodily, digital or cloud environments to some other vacation spot — reduces migration threat and has the added benefit of decreasing long-term vendor lock-in.
Find out how to keep away from three dangers most groups underestimate throughout migration
Even essentially the most rigorously deliberate and executed migrations can fail for predictable causes.
1. Groups typically underestimate deliberate downtime
Too many groups plan for a perfect degree of downtime versus a worst-case situation. Sadly, migrations regularly stretch past upkeep home windows. If a window closes when programs aren’t steady, organizations can undergo missed transactions, stalled operations, SLA violations and reputational harm.
That’s why migration planning should embrace a proper enterprise continuity technique, Ask upfront:
- How lengthy can every workload realistically be offline?
- What occurs if rollback is required?
- Who makes the go or no-go determination?
- What’s the communication plan if restoration time exceeds expectations?
Backup and restoration are essential. The flexibility to shortly restore workloads to their unique platform can imply the distinction between a brief delay and a multi-day outage.
2. Backup and restoration gaps can plague transitions
Migration creates a harmful grey zone for backup and catastrophe restoration, with environments are sometimes cut up between outdated and new platforms. That’s when recoverability have to be strongest. The time it takes to revive backups from both surroundings is essential.
Widespread gaps seem when:
- Backup chains are damaged throughout VM exports.
- Incremental backup jobs might fail after platform conversion.
- Software-consistent snapshots aren’t validated on the brand new hypervisor.
- DR replication targets aren’t synchronized throughout phased cutovers.
Backup and restoration should operate repeatedly all through the migration. IT groups want to keep up parallel safety throughout overlap intervals in order that workloads are recoverable from each the legacy and goal platforms till the transition is completed.
3. An increasing assault floor means backup photos want safety
Migration additionally expands your assault floor.
With two hypervisor stacks operating, complexity spikes. Backup repositories, an image-level backups specifically, can change into high-value targets. If attackers compromise them throughout migration, your rollback and restoration choices disappear.
Immutability is important throughout this part. IT groups want to guard backup photos towards modification or deletion, even by privileged accounts. They should tighten role-based entry controls and restrict administrative entry.
Equally necessary is adherence to the 3-2-1 precept: Not less than three copies of information, on two totally different media varieties, with one copy saved off-site or offline. Throughout migration, that third copy turns into essential insurance coverage.
If each manufacturing and first backup infrastructure are affected, an remoted copy preserves your restoration path.
The worth of a natively built-in platform
Sustaining parallel safety is important as a result of it lowers operational threat. Nonetheless, it additionally will increase administration complexity. Two hypervisor stacks, a number of storage programs and parallel safety insurance policies should coexist with out creating gaps.
A unified cyber safety platform can simplify this course of for IT groups. A unified cyber safety platform can cut back complexity by delivering constant backup, restoration and safety controls throughout bodily servers, hypervisors and cloud workloads by means of a single level of management.
Natively built-in safety and migration capabilities in Acronis Cyber Defend can cut back transition timelines whereas sustaining rollback readiness and steady synchronization.
Migration as a resilience alternative
The shift away from VMware has made one idea clear: Migration planning is a long-term competency, not a one-time undertaking.
Groups that succeed deal with hypervisor transitions as resilience workout routines. They validate backups upfront, guarantee cross-platform restoration functionality, keep rollback paths, harden backup storage towards ransomware and confirm knowledge integrity after cutover.
With these safeguards in place, migration turns into extra predictable and considerably extra prone to succeed.
VMware migrations don’t must be sluggish, dangerous or disruptive.
With Acronis Cyber Defend, IT groups acquire a versatile, responsive platform that accelerates migration whereas delivering AI‑powered safety, backup and restoration in a single natively built-in resolution.
