The Definitive Guide to Migrating from NSX-V to NSX-T


The Definitive Guide to Migrating from NSX-V to NSX-T

VMware NSX has been revolutionizing network virtualization and security since its inception. The latest generation, NSX-T, takes it to the next level with a completely re-architected design, robust feature set, and support for diverse modern workloads.

As NSX-V nears end-of-life, organizations face an important decision – whether to migrate to NSX-T. This comprehensive guide covers:

  • Powerful new capabilities in NSX-T 
  • Technical architecture and components
  • Key differences between NSX-V and NSX-T
  • The detailed step-by-step migration process
  • Training options to develop NSX-T skills
  • The compelling business drivers for upgrading to NSX-T

Let’s dig in and illuminate what’s involved in making the move.

Transforming Networking, Security, and Operations with NSX-T

NSX-T revolutionizes private and public cloud networking. Key capabilities include:

  • Automated provisioning, configuration, and management via API-driven architecture. Speeds network deployment.
  • Native integration with Kubernetes, OpenStack, public clouds, and VMware Cloud Foundation. Enables multi-cloud networking.
  • Micro-segmentation, distributed firewall, IDS/IPS, malware prevention, and advanced threat detection. Stops lateral attack propagation.
  • Unified networking and security across containers, VMs, bare metal, and any endpoint on the logical switch fabric.
  • Declarative policy framework, consumer-focused UI, REST APIs, and ecosystem integration. Simplifies operations.

In summary, NSX-T combines simplified operations, multi-cloud agility, and a radical advance in security.

NSX-T Architecture and Components

NSX-T has a fundamentally new architecture optimized for cloud-native apps and multi-cloud environments. Key components include:

  • NSX Manager – Centralized network management, monitoring, and configuration plane.
  • NSX Controller – Distributed state management for logical switches and routers. Provides programmability.
  • NSX Edge – Gateway services for north-south routing, VPN, DHCP, and load balancing.
  • Distributed Logical Routers and Switches – East-west routing and switching between workloads and endpoints.
  • Security Components – Distributed firewall, IDS/IPS, malware prevention, and analytics.

This architecture delivers optimized performance, scalability, and resiliency.

How NSX-T Differs from NSX-V

While both provide network virtualization, NSX-T differs from NSX-V in:

  • Multi-hypervisor support – NSX-T works with KVM, ESXi, and cloud-native platforms. NSX-V is ESXi-only.
  • Controller architecture – NSX-T has distributed controllers. NSX-V controllers are centralized.
  • Management plane – NSX-T uses cloud-native APIs and UI. NSX-V has vSphere-centric management.
  • Gateway support – NSX-T has distributed gateways. NSX-V uses centralized NSX Edge.
  • Security – NSX-T has native advanced security. NSX-V requires additional products.

These differences make NSX-T ideal for rapidly provisioning and securing modern multi-cloud applications.

Step-by-Step Migration Process

Migrating from NSX-V to NSX-T involves:

  1. Audit existing NSX-V deployment – document all logical switches, routers, security policies, and integrations.
  2. Build NSX-T sandbox – create NSX Manager, controllers, edges, logical switches, and routers. Test thoroughly.
  3. Take NSX-T training – develop expertise in operations, management, security, and troubleshooting.
  4. Develop a detailed migration plan and validate all steps/timing to minimize application downtime.
  5. Deploy NSX-T in parallel to NSX-V – add NSX-T components to infrastructure.
  6. Migrate app tier-by-tier – apply NSX-T policies to each app tier, define IPs, and cut over traffic.
  7. Retire NSX-V – once all apps are on NSX-T, remove NSX-V components.
  8. Optimize, tune, and monitor NSX-T – fine-tune performance, availability, and security posture.

With careful planning and execution, organizations can migrate seamlessly to NSX-T.

The Business Case for NSX-T Migration

Upgrading to NSX-T enables organizations to:

  • Enhance security and reduce risk exposure through micro-segmentation and native threat prevention.
  • Speed up deployment of new apps and services through automation.
  • Reduce TCO by consolidating network and security stacks.
  • Support modern containerized and cloud-native applications.
  • Gain operational agility to respond faster to business needs.

For organizations running NSX-V, migrating to NSX-T is a strategic opportunity to transform networking, security, and IT delivery. With end-of-support looming, now is the time to start planning the transition.
