Broadcom made your VMware renewal non-negotiable. Now you're facing a forced hypervisor migration — and every wrong move risks dropping calls for thousands of users. We architect the evaluation and execute the transition so nothing falls through the cracks.
Broadcom's licensing changes have removed "stay on VMware" as a viable option. Organizations running Cisco UC (UCCX, CUCM, IM&P, CUPS) on vSphere are now evaluating alternatives — on a timeline they didn't choose.
Most organizations running Cisco UCCX have VMware in their stack because it was the default. Now Broadcom's pricing has forced a decision that intersects directly with your UC infrastructure — and the teams responsible for the hypervisor rarely talk to the teams responsible for call flows. That's where calls get dropped.
There's also a compounding factor: the organizations in this position are often the same ones already evaluating UCCX → Webex CC migration. So you're managing a hypervisor transition and a contact center platform transition at the same time — which means the hypervisor choice you make today constrains your migration path for the next 3–5 years.
Broadcom's pricing shifts have invalidated the assumption that VMware is the safe, cost-effective choice. The TCO calculus has changed overnight.
Server teams plan the VMware exit. Contact center admins find out after the migration window is set. The call flow impact gets discovered at 2am.
Renewal deadlines create artificial urgency. Organizations make fast hypervisor decisions that lock them into a UC platform for years — sometimes without realizing it.
Not every option works for every contact center. Nutanix AHV supports UCCX in production — but the migration process is non-trivial. We evaluate all three paths against your call volume, current UCCX version, and planned cloud migration timeline.
The most common destination for Cisco UC re-platforming. AHV is a Type 1 hypervisor built into Nutanix HCI — no licensing overhead, predictable TCO, Cisco UC validated.
Cisco maintains a compatibility matrix for UC workloads. If you're already in the Cisco ecosystem, NFVIS or Cisco-validated hypervisors may simplify support relationships.
KVM, Hyper-V, or public cloud virtualization — evaluated when your UC stack or licensing situation makes A or B impractical. Rarely first choice, but sometimes the right answer.
Written analysis of all viable options for your specific UC stack, call volume, and budget — with a clear recommendation and supporting rationale.
Call flow impact analysis across your UCCX scripts. Identifies which routing strategies, VXML apps, and Finesse customizations are at risk during the VM migration.
Step-by-step migration plan with rollback triggers. Call flows tested post-migration before the window closes — not discovered broken on Monday morning.
If you're also planning a UCCX → Webex CC move, we evaluate how your hypervisor decision affects that timeline and build a unified migration roadmap.
This isn't a generalist hypervisor consultation. Jim has spent his career in Cisco contact centers — design, migration, cutover, and long-term support. He knows which VMware migration steps will break UCCX call flows, and which won't. He brings the same depth of knowledge to hypervisor planning that he brings to UCCX migrations.

A 60-minute discovery call maps your current UC environment, your renewal timeline, and your options. No vendor pitches — just a UC engineer who's done this before.
