Open-source multi-platform migration planning

Plan virtualization migrations with better inventory, dependency, and readiness data.

Viaduct helps teams inspect multi-platform environments, understand workload relationships, prepare migration plans, and create reviewable reports before a pilot.

It is built for virtualization admins, infrastructure managers, and IT architects who need a clear view of what exists, what depends on what, and what should be checked before moving workloads.

What Viaduct does

Prepare the migration conversation before making changes.

Inventory environments

Collect normalized inventory from supported virtualization platforms.

Map dependencies

Review workload, network, storage, and backup relationships before grouping moves.

Build migration plans

Create plans from declarative specs, selectors, readiness checks, approvals, and waves.

Run readiness checks

Check configuration, policy, backup coverage, and runtime prerequisites before a pilot.

Create review reports

Export summaries that reviewers can use during planning, approval, and handoff.

Platform support

Inspect common virtualization platforms, with validation status documented.

Viaduct includes connectors for VMware, Proxmox, Hyper-V, KVM, and Nutanix inventory. Veeam support is available for backup and restore-point enrichment. Community connectors can be loaded through the plugin host.

Some connector validation is fixture-backed. Review the support matrix before using Viaduct in a live environment.

Safe evaluation

Try Viaduct with included KVM sample data.

No live hypervisor is required for the first run. The quickstart uses the included KVM fixtures so you can open the dashboard, create an assessment, inspect inventory, view dependencies, save a plan, and export a report locally.
