VMware NSX to Cilium Migration – Senior Engineers, Fixed Scope
Yes, migrating from VMware NSX to Isovalent Cilium is a well-understood project. We run side-by-side cluster deployments to ensure continuous pod-to-pod and egress connectivity.
The lowest-cost way off VMware NSX: our migration tooling automates the repetitive work —you pay senior engineers for judgment, not keystrokes.
How we support VMware NSX → Isovalent Cilium after migration
- ✓Side-by-side clusters eliminate traffic drops.
- ✓Senior platform engineers execute fixed-scope projects.
- ✓Vendor support active during your timeline.
- ✓Post-migration managed Cilium operations.
- ✓40–70% savings on legacy platform support.
- ✓24/7 US-based support throughout the move.
Integration with physical network
Your physical network fabric is tightly coupled with NSX-T NCP routing. A wrong move could break connectivity.
Preserving pod security rules
Custom NSX Security Groups applied to pods must translate into CiliumNetworkPolicies without gaps.
Pressure to move off NSX-T
Uncertainty around licensing and support for container networking (NCP) accelerates the timeline.
VMware NSX → Isovalent Cilium migration — your questions answered
How do we avoid traffic drops during the migration?+
We run a parallel cluster next to your existing NSX-T deployment. Traffic gradually shifts to Cilium while NSX-T remains operational. Your vendor contract stays intact, so you control the cutover window.
Our pods rely on custom NSX Security Groups. Can we preserve those policies?+
Yes. Our engineers map NSX security groups to CiliumNetworkPolicies before any pods move. We test equivalent rules in the side-by-side cluster first.
Will this work with our existing physical network fabrics controlled by NSX-T NCP routing?+
Yes. We configure the Cilium cluster to interoperate with your physical network. The routing is validated during the side-by-side phase. No rip-and-replace required.
What triggers organizations to migrate from NSX-T to Isovalent Cilium?+
Many teams modernize container infrastructure, move off VMware Tanzu/NCP, or respond to evolving vendor licensing. Our fixed-scope approach removes uncertainty.
