Moderator: Thread moved to the VCP area.
VCPs do NOT need renewing nowadays, but they can be updated to newer versions to show that you are “current”.
What VCPs do you already have?
I am planning to get VCP-NV-2020.
I wonder where can I download software for NSX v6.2?
So you are not renewing a certification, but wish to achieve VCP-NV 2020.
Why you posted in the vSphere area when you want the NSX certification I don’t know.
I see you also previously posted a vSphere question in the VCP area - please help us moderators by posting in the appropriate area in the first place.
You can run NSX HOLs for free: Try VMware NSX Hands on Lab for Free | VMware | UK
Or evaluate It for a year for a small fee: https://www.vmug.com/vmug2019/membership/evalexperience
