In today’s rapidly evolving IT landscape, Cloud Service Providers need to ensure that their customers have access to the latest and most advanced networking and security features. VMware Cloud Director (VCD) allows customers to build secure private clouds, dramatically increasing data center efficiency and business agility.
Combined with VMware NSX (previously NSX-T Data Center or NSX-T), VMware’s software-defined networking platform, the result is a powerful solution for service providers and enterprises to support the growing number of distributed applications being run on heterogenous endpoints, VMs, containers, and bare metal across DC, Cloud, and Edge.
Why should we migrate VMware Cloud Director to VMware NSX (NSX-T)?
As per the current latest version (10.4.2), VCD still supports two options for network virtualization: NSX Data Center for vSphere (NSX-V) and VMware NSX (formally known as NSX-T Data Center or NSX-T). However, NSX-V reached its End of General Support (EoGS) is January 16, 2022, and technical guidance on January 16, 2023. Therefore organizations must take proactive steps to mitigate security risks, maintain compliance, and continue to leverage the benefits of network virtualization.
The migration process can be complex and should be planned and executed carefully to minimize disruption and ensure a successful transition. Recently, VMware has released version 1.4.2 of the VMware NSX Migration for VMware Cloud Director tool, enhancing the support of VCD networking features and allowing V2T migrations with minimal downtime.
VCD V2T Features and Migration Matrix
To help Cloud Service Providers plan for a smooth transition, this short blog provides information on the current VCD NSX Features Support Matrix and those that can be auto-migrated using the latest NSX Migration for VCD tool (1.4.2).

Conclusion
While VMware NSX Data Center for vSphere (6.4.x) continues to function past its EoGS date, bug fixes and security patches for the specific version are discontinued. This can expose the infrastructure to vulnerabilities, making it crucial for organizations to plan and execute an NSX-V to NSX-T transition for VMware Cloud Director environments.
In addition, migrating to NSX-T will maintain a strong integration to your VMware Cloud Director platform while enabling greater business agility, cloud scalability, and network performance by supporting modern distributed apps with a complete networking and security stack.
