🚀 Automating NSX Assessment for NSX-T Migration with PowerShell
Automation is one of the core pillars of modern virtualization operations. The script and workflow presented below are designed to help administrators export NSX data, streamlining the assessment and planning process for NSX-T migrations.
This migration is essential for supporting various VCF versions and ensuring alignment with current, fully supported architectures.
When working with NSX, leveraging PowerShell accelerates operational tasks, standardizes configurations, and significantly reduces manual errors—delivering greater predictability and control during platform transitions.
In this post, I'll share the key repositories and show you how to set up your PowerShell environment to get started with PowerNSX and NSX-PowerOps.
📦 GitHub Repositories
🔹 PowerNSX (Archive)
Official (archived) repository with cmdlets for NSX automation:
🔹 NSX-PowerOps
