That's a very specific career trajectory. I hold a VCP-DCV, but I didn't come from an NV background like you, so take this for what it's worth... I found the VCP-DCV training and exam to be pretty straight-forward. Having worked with NSX-T in production environments, my opinion is that if you've managed the network side of a vSphere environment, then the data center side should look very familiar and be a better transition than the other way around. It's easier, at least from my experience, to work with DC infrastructure than network infrastructure. One thing you might want to brush up on is some of the CLI management tools, like PowerCLI and the ESXi shell (for example, the esxtop utility). Also, be sure to learn the different storage protocols. Hope this helps!
