Upgrading NIOC from version 2 to 3 is no big deal. But I’m writing this blog post because the official VMware documentation says that the upgrade to NIOC v3 is disruptive and that worried me.
We have only one dvSwitch in our virtual infrastructure and use vSAN and NSX. If this upgrade is really disruptive, we need to shut down all virtual machines before the upgrade process starts. And that would be a big deal for us and our customers.
