# Why clinics face a decision now Broadcom's acquisition of VMware removed perpetual licenses and raised subscription costs. Health systems with expiring legacy contracts must either absorb higher fees or move to an alternative platform. For clinics, the main barrier to switching is fear of downtime: infrastructure supports scheduling, billing, PACS, and other systems that must stay available during patient care.
# Infrastructure (HCI) changes the migration problem HCI replaces separate servers, storage networks, and hypervisors with a single operating layer. For many non-EHR workloads—clinical databases, scheduling, imaging, billing—this lets teams migrate the underlying infrastructure without changing application code.
HCI advantages callers out in practice:
- Migrate applications as-is, avoiding costly re-architecting of non-EHR systems.
- Combine compute and storage into defined nodes to avoid surprise fees and simplify licensing.
- Isolate resource-heavy workloads (for example, PACS) into dedicated pools so large files don't slow primary EHR performance.
# Migration approach that avoids clinical downtime The practical method described uses a continuous replication workflow:
- 1Parallel setup: Configure the new HCI platform alongside the active VMware environment.
- 2Background mirroring: Continuously replicate data while clinicians work normally.
- 3Off-hours cutover: Perform the final synchronization and switch during a brief, scheduled window. Keep the legacy VMware environment intact as a rollback option.
This sequence minimizes interruption because the production environment remains live until the final cutover.
# Compliance and audit readiness during and after migration HCI platforms discussed in the article include built-in safeguards for encryption at rest, role-based access controls, and continuous system activity logging. These features provide the audit trails insurers and auditors require. When choosing an HCI deployment, pick between:
- Multi-tenant model: Shared physical hardware with logical separation of patient records.
- Dedicated model: Hardware reserved solely for your organization to eliminate shared-tenant exposure.
# Who should execute migration: in-house or managed partner
A managed cloud provider can take responsibility for:
- environment.
- Monitoring background replication and executing the off-hours cutover.
- Handling ongoing patching, hardware monitoring, and incident response after migration.
Pairing HCI with a managed partner distributes operational risk and frees internal staff to focus on clinical IT priorities.
# Practical checklist for a migration project
- Inventory all non-EHR workloads that run on VMware and prioritize by clinical impact.
- Select HCI platform and decide between multi-tenant or dedicated hardware.
- Establish continuous replication and test synchronization in a non-production window.
- Schedule a short off-hours cutover with rollback plans and verify audit logging and encryption.
- Decide whether to house operations internally or engage a managed cloud provider for cutover and ongoing maintenance.
# Bottom line Moving off VMware is driven by licensing and cost changes. A parallel HCI deployment with continuous replication enables many clinics to migrate infrastructure without taking clinical systems offline. For organizations with limited IT bandwidth, a managed cloud partner can lower operational risk and handle the day-to-day work after cutover.
