What is VMware NSX-V to NSX-T Migration?

In this article, we will discuss VMware NSX-V to NSX-T Migration in detail.

To run virtual machines, there exists a requirement for physical servers with hypervisors.

Modern data centers use these physical servers to bring out the scalability and cost-cutting effectiveness in the era of virtualization.

VMware is one of the world’s largest network virtualization providers.

The SDN (Software-defined networking) model offers all the required characteristics to build complicated configurations of networks. It provides security and enables easy scaling without amending changes.

What is NSX?

VMware NSX is a network virtualization and security platform that enables organizations to create and manage virtual networks in a software-defined data center. It provides a network virtualization layer that abstracts the physical network hardware, allowing for greater flexibility, scalability, and security.

NSX enables the creation of virtual networks decoupled from the underlying physical network hardware. This allows organizations to create and manage networks in a more agile and efficient way, reducing the time and effort required to provision, configure, and manage network infrastructure. NSX also enables micro-segmentation, which allows organizations to create granular security policies based on application-level requirements.

Some of the key features and capabilities of VMware NSX include:

  1. Network Virtualization: NSX allows organizations to create virtual networks decoupled from the underlying physical network hardware, providing greater flexibility and agility.
  2. Micro-segmentation: NSX enables the creation of granular security policies based on application-level requirements, providing enhanced security and compliance.
  3. Distributed Firewall: NSX includes a distributed firewall that provides granular security policies at the virtual machine level, enabling fine-grained control over network traffic.
  4. Load Balancing: NSX provides load-balancing capabilities that allow organizations to distribute traffic across multiple virtual machines and application servers, improving performance and availability.
  5. Automation and Orchestration: NSX provides APIs and integrations with automation and orchestration tools, enabling organizations to automate the provisioning and management of virtual networks.

VMware NSX is a powerful platform that enables organizations to create and manage virtual networks in a software-defined data center, providing greater flexibility, agility, and security. VMware created VMware NSX to manage the fastest growth of data center networking requirements.

There are two versions of NSX. The two variants of NSX are known as NSX-V and NSX-T.

This blog depicts more information about -What are NSX-V and NSX-T. and What is VMware NSX-V to NSX-T Migration?

So, to know more about it, let’s have a detailed discussion of each one by one.

What is NSX-V?

NSX-V (NSX for vSphere) is the first version of VMware’s NSX network virtualization and security platform that was designed to integrate with VMware’s vSphere virtualization platform. 

NSX-V provides a software-based network virtualization layer that enables organizations to create, provision, and manage virtual networks in a data center. It allows organizations to abstract the physical network infrastructure from the virtual infrastructure, providing a more flexible and agile network infrastructure.

Integration with vSphere becomes easy when NSX-V connects with vCenter.

However, NSX-V comes with drawbacks. It wasn’t possible to connect NSX-V with more than one vCenter.

Also, the sustenance becomes clumsy and unmanageable. Therefore, to tackle the workload in many companies, the VMware NSX-V solution turns out to be unmatchable for several clients.

So, like this NSX-T’s introduction took place and NSX-T replaced NSX-V.

What is NSX-T?

NSX-T (NSX for Multi-hypervisor and Container Environments) is the next generation of VMware’s NSX network virtualization and security platform. NSX-T is designed to support multiple hypervisors, bare-metal servers, and container environments. 

It provides a software-based network virtualization layer that enables organizations to create, provision, and manage virtual networks in a data center.

NSX-T has several new features and capabilities that differ from NSX-V:

  • Multi-hypervisor support: NSX-T supports not only VMware vSphere but also other hypervisors such as KVM, Microsoft Hyper-V, and Docker containers.  NSX-T supports multiple hypervisors and bare-metal servers, enabling organizations to use the same network virtualization and security platform across a wider range of infrastructure environments.
  • Container support: NSX-T has native support for container environments, enabling organizations to manage and secure container-based workloads alongside traditional virtual machines.
  • Cloud-native networking: NSX-T provides support for cloud-native applications and microservices, enabling organizations to deploy and manage container-based workloads with ease.
  • Layer 2 to Layer 7 networking and security services: NSX-T provides a comprehensive set of Layer 2 to Layer 7 networking and security services, including distributed routing, load balancing, VPN, Layer 7 application-aware firewalling, distributed intrusion detection and prevention, and automated security policy enforcement and more.
  • Network segmentation: NSX-T enables organizations to create micro-segmentation and granular security policies based on application-level requirements, providing enhanced security and compliance.
  • Distributed networking and security: NSX-T provides a distributed architecture that allows organizations to scale and distribute networking and security services across multiple clusters and sites.
  • Simplified architecture: NSX-T has a more simplified and modular architecture than NSX-V, making it easier to deploy and manage at scale.

VMware NSX-T is built from the ground level and what lies in it is different from NSX-V.

Moreover, many people mistook the NSX-T as an upgrade of VMware NSX-V. The ultimate benefit of the VMware NSX-T is that one can have several Center servers.

One does not require deploying a Center at all. Instead, they can opt for ESXi as the operating system in the VMware NSX-T GUI.

VMware NSX-V to NSX-T Migration

There occurs a need for VMware NSX-V to NSX-T Migration.VMware NSX-V to NSX-T migration can be done in a phased manner to minimize disruption to the environment.

The VMware NSX-V to NSX-T Migration involves moving network virtualization functionality from the NSX-V platform to the NSX-T platform.

VMware NSX-V to NSX-T Migration process enables customers to benefit from enhanced capabilities and new features of NSX-T.

The VMware NSX-V to NSX-T Migration consists of planning, preparation, and execution steps, such as upgrading the vSphere environment, preparing the NSX-T environment, migrating NSX-V configuration to NSX-T, testing and validating the new environment, and finally decommissioning the NSX-V environment.

For VMware NSX-V to NSX-T Migration, VMware offers migration tools and resources to help customers perform this migration efficiently and effectively.

One can select between the two NSX migration methods which are In parallel (Lift and Shift) and In Place (Migration Coordinator).

Top Reasons to Opt for VMware NSX-V to NSX-T Migration

Migrating from NSX-V to NSX-T can provide organizations with a more modern, flexible, and scalable network virtualization and security platform that supports a wider range of infrastructure environments and cloud-native applications. 

However, it is important to carefully plan and execute the migration to ensure a smooth transition and avoid disruption to critical workloads.

VMware NSX-V to NSX-T Migration’s need is there as new characteristics are added to NSX Data Center.

To have benefited from the new changes, NSX-T is a good option to go ahead with.

As NSX-V is dependent on vSphere, thus it cannot keep up with new trends and rising demands.

While NSX-T allows one to expand to the cloud due to its dynamic nature, also, NSX-T also offers NSX across several hypervisors.

The most important advantage of the VMware NSX-V to NSX-T Migration is that it offers security.

VMware NSX-V to NSX-T Migration comes with continuous developments for new security features.

Another advantage of VMware NSX-V to NSX-T Migration includes vSphere and Center independence, support for modern applications, support for containerized workloads, advanced tools for network traffic monitoring, etc.

VMware NSX-V to T End Of Support

VMware NSX-V (NSX for vSphere) reached its end of general support on January 16, 2022. It means that VMware will no longer provide technical support, software updates, or security patches for NSX-V after this date.

However, customers who have active support contracts for NSX-V can still receive technical assistance through VMware’s Extended Support program, which provides an additional two years of support beyond the end of the general support date.

It is necessary for organizations that are still using NSX-V to plan for migration to the latest version of VMware NSX-T (NSX for Multi-hypervisor and Container Environments), which is the recommended replacement for NSX-V. 

Thus, this decision makes an impact on NSX-V customers to migrate to NSX-T. As NSX routes at the hypervisor level, this migration process is not an easy one to accomplish.
