As VMware NSX-V reached end of support, many service providers faced an urgent challenge: modernize their networking infrastructure without disrupting customer services.
This was the situation for one of North America’s largest managed service providers and a Broadcom Pinnacle Partner. Operating a complex multi-datacenter environment, the company needed to migrate from VMware NSX-V to VMware NSX-T while maintaining service continuity across its cloud infrastructure.
To achieve this, the organization partnered with comdivision to design and execute a structured, low-risk migration strategy.
The Challenge: Migrating from NSX-V to NSX-T Across Multiple Data Centers
The provider’s existing VMware NSX-V environment had reached the end of vendor support.
Continuing to operate on an unsupported platform introduced several risks, including:
- increased operational risk,
- limited vendor support,
- reduced security,
- inability to adopt future VMware technologies,
- and growing infrastructure complexity.
At the same time, the migration needed to be performed across multiple production data centers while minimizing disruption for customers.
As the Head of Infrastructure explained:
“We knew where we wanted to go, but moving off NSX-V required the right expertise. comdivision supported us throughout the migration and made the transition straightforward.”
Why the Customer Chose comdivision
The organization had maintained a long-term partnership with comdivision and trusted the team’s deep expertise in VMware networking and large-scale service provider environments.
Rather than simply performing a technical migration, the customer needed support with:
- architecture design,
- migration planning,
- infrastructure validation,
- risk reduction,
- and hands-on migration execution.
The goal was to establish a fully supported networking platform while creating a repeatable migration model for future data centers.
What comdivision Delivered
The engagement focused on designing and executing a structured VMware NSX-V to NSX-T migration.
The project included:
- comprehensive infrastructure assessments
- evaluation of configurations and software versions
- hardware readiness validation
- VMware NSX-T architecture design
- migration strategy development
- migration testing and validation
- hands-on migration support
- collaboration with the customer’s engineering teams
- migration of the first five production data centers
- development of a repeatable migration framework for future deployments
The structured approach allowed the customer to begin production migrations within 48 hours after the assessment.
Technology Stack
The migration project was built around VMware’s software-defined networking technologies, including:
- VMware NSX-T
- VMware NSX-V
- VMware vSphere
- Broadcom CSP / VCSP infrastructure
- Multi-datacenter cloud architecture
This provided a modern networking foundation capable of supporting future VMware Cloud Foundation deployments.
The Results
The migration delivered significant operational and strategic improvements.
Key outcomes included:
- successful migration from VMware NSX-V to VMware NSX-T
- supported networking platform for production workloads
- reduced operational risk
- initial production migrations completed within 48 hours
- repeatable migration methodology for additional data centers
- minimized customer impact throughout the migration
- foundation for future VMware Cloud Foundation adoption
- continued strategic partnership with comdivision
The organization now operates on a supported networking platform that is ready for future infrastructure modernization.
Why Migrating from NSX-V Matters
Many organizations continue to operate legacy NSX-V environments despite the end of vendor support.
However, unsupported networking platforms create long-term challenges, including:
- security concerns,
- compliance risks,
- limited upgrade paths,
- higher operational costs,
- and increased technical debt.
Migrating to VMware NSX-T provides organizations with a modern software-defined networking platform designed for today’s private cloud and VMware Cloud Foundation environments.
A Structured Migration Minimizes Risk
Large-scale networking migrations require far more than technical execution.
Success depends on:
- detailed infrastructure assessments,
- architecture validation,
- migration testing,
- phased deployment,
- and close collaboration between engineering teams.
By investing in planning before implementation, organizations can reduce downtime, minimize business risk, and accelerate modernization.
Conclusion
By partnering with comdivision, this global service provider successfully modernized its multi-datacenter networking infrastructure through a structured migration from VMware NSX-V to VMware NSX-T.
The engagement delivered:
- a fully supported VMware NSX-T platform,
- reduced operational risk,
- rapid migration execution,
- repeatable deployment processes,
- a scalable networking architecture,
- and a future-ready foundation for VMware Cloud Foundation.
For organizations planning an NSX-V to NSX-T migration, modernizing multi-datacenter VMware networking, or preparing for VMware Cloud Foundation, a structured migration strategy combined with experienced architectural guidance significantly reduces risk while accelerating infrastructure transformation.
