Broadcom Pulls VMware VDDK: How to Navigate Migration Challenges

Short answer: no. You are not stuck. Broadcom pulled public access to the VMware Virtual Disk Development Kit (VDDK). That makes some migration tools harder to use. But it does not close your exit from VMware.

Here's why. The VDDK sits at the data-transfer layer. That's the part that copies virtual disk data out of vSphere. It is not the part that plans and runs your migration. So the fix is simple. Stop treating your VMware exit as one tool you depend on. Run it as a program instead. Build that program so it does not rely on any single transfer method. That's the layer where ReadyWorks and VirtualReady work. And it's the part this change does not touch.

If you are a Broadcom customer and this feels like one more headache, that's fair. It is another surprise in a long line of them. And it lands right when renewal costs and tight budgets are already a problem. But the good news holds. This hits the tools, not your ability to leave. Here's what changed, which tools are affected, and how to plan an exit that does not depend on one download.

What is the VMware VDDK, and why does it suddenly matter?

The VDDK is a VMware library. It lets software read and write VMware virtual disks from outside the hypervisor. Most admins never downloaded it themselves. It just sat underneath the migration and backup tools they used every day. As ShapeBlue explains, the VDDK is what lets third-party software read VMware virtual disks. Vendors have always pointed customers to a Broadcom page to get it.

Here's why that matters. One vendor download became a hard requirement for much of the migration ecosystem. When that download goes away, a lot of tools feel it at once.

What did Broadcom actually change?

Broadcom removed the public VDDK download pages. Links that vendors and customers used now return 404 errors. ShapeBlue documented this on August 25, 2026. The VDDK pages listed in VMware-to-KVM docs started failing. That included the paths for VDDK 8 and 9. So far there is no official Broadcom announcement. There is no stated replacement either. The Virtualization Howto write-up covers the wider impact.

One thing makes this harder to work around. The VDDK license does not allow general redistribution. So migration and backup vendors cannot legally mirror the files or ship them in their installers. That's why you can't just find the download somewhere else.

Which migration tools are affected by the VDDK removal?

The change affects tools that use the VDDK to pull disk data out of vSphere. It does not affect every migration path. Here's how the common cases break down.

The affected side is backed by the Red Hat support article on MTV, Microsoft's updated Azure Migrate guidance, and reports from the Nutanix community. Check the exact method your target platform uses. One product can offer both a VDDK path and a non-VDDK path.

Does the VDDK removal block every VMware migration?

No. This is a tooling problem, not a wall. Agent-based, storage-assisted, and proxy-based methods do not need the VDDK. The Proxmox native import tool never used it. What changed is this. You can no longer assume the default transfer method will work. Now you have to ask one question early. How does this tool get the data out of vSphere, and does it need the VDDK?

For most teams, the real cost is not a hard stop. It's added uncertainty. And that lands on a project that already covers hundreds or thousands of workloads. When the transfer layer is shaky, planning and coordination matter more, not less.

Why does this feel worse than a missing download?

Because it arrives with everything else. Many customers are already facing steep renewal quotes. Platform9 has reported renewal increases of 300 to 1,500 percent across the install base. That's a vendor figure, so treat it as rough, not exact. You can read their view in the Platform9 write-up. Add rising memory costs and tight budgets on top. Then a quiet change to a developer library starts to feel like a plan.

Each role feels it differently. A CIO worries about compliance and a timeline the business can trust. An SVP or VP of IT Infrastructure worries about budget and staying in control of the roadmap. A Solutions Architect has to re-check a migration design under a deadline. But it points to the same lesson. Your exit plan should not depend on one tool a former vendor can switch off.

How do you migrate off VMware without depending on the VDDK?

Split the migration into two layers. Then manage them apart.

• The transfer layer moves the data. This is where the VDDK question lives. Pick a method your target platform supports without the VDDK. Agent-based, storage-assisted, or native import all work. Confirm it before you commit.
• The program layer plans and runs the migration. This is dependency mapping, wave planning, sequencing, coordination, and tracking. It does not care which tool moves the data.

Build the program layer so it works with any transfer method. Then a change like this becomes a small swap, not a full reset. You change how the data moves. You do not re-plan the whole migration.

Where does VirtualReady fit in a VDDK-free plan?

VirtualReady works in the program layer, above the transfer tool. It handles the parts a transfer tool does not. It maps application and infrastructure dependencies. It plans migration waves. It sequences the moves. It coordinates the people involved. And it tracks progress to the end. It is not tied to one transfer tool. So it works with whatever VDDK-free method your target platform uses, in most cases.

Most teams should start with visibility. Without a clear, current picture of your VMware estate and its dependencies, every choice after that is a guess. That includes which transfer method to pick. A VM Accelerator estate assessment is a low-effort way to get that picture first.

Plan your VMware exit as a program, not one download

Broadcom pulling the VDDK is a real hassle. It's fair to be annoyed by it. But it changes how some tools move data. It does not change whether you can leave. Teams that run migration as a program handle changes like this without losing the timeline. Keep visibility and dependency mapping at the center. Treat the transfer method as a part you can swap.

Start with a clear view of your estate. Then pick the transfer method that fits your target. To map your dependencies and plan your waves, talk to the ReadyWorks team. Or start with a VM Accelerator estate assessment.

FAQ

Does Broadcom pulling the VDDK mean I cannot leave VMware?

No. The VDDK is a data-transfer tool used by some migration software. Methods that skip it still work. That includes agent-based, storage-assisted, and the Proxmox native import tool. Your ability to plan and run a migration is not affected.

Which VMware migration tools need the VDDK?

Tools that read disk data from outside the hypervisor often need it. That includes Azure Migrate agentless migration, Nutanix Move, Red Hat MTV, the CloudStack VMware-to-KVM path, and tools built on virt-v2v or nbdkit. Many of these also offer a non-VDDK path. So check the specific method before you commit.

How do I migrate off VMware without the VDDK?

Pick a transfer method your target platform supports without the VDDK. Then run the migration as a program that does not depend on that one tool. Keep dependency mapping, wave planning, and coordination in a layer that stays the same when the transfer method changes. That's the role VirtualReady plays, in most cases.
