We have a currently running nutanix cluster on dells and are looking to move the cvms to a new subnet. The new subnet has esxi management for each host, but on a different vmk, is it possible to point the cvms to the new vmk to get around the 'CVM subnet is currently different than the Hypervisor subnet.' issue?

Not trying to twist your arm, just want to make this easy as possible for yall. Feel free to reach out jon at nutanix dot com, happy to chat with you and your network team to work through the options.
Our networking team is reviewing, still may reach out to you, these are our first nutanix, impressed so far, just this networking issue is slowing down the implementation.
Assuming that the TOR's are VPC enabled, they will have VPC enabled VLANs for everything, so that failover is "sane"
If you want to delve into this more, reach out at jon at nutanix dot com and I'm happy to chat through this on a webex
Believe this is due to not being able to run a vpc across the TOR.
It looks like I can do that by changing the current ip of the cvms to that subnet and adding esxi mngmt interfaces in there, then having a dual homed box for management.
Downtime is ok as this is our first nutanix setup and its all in test mode at the moment.
That said, it sounds like you want to do this online. As laid out in the KB, you'd have to follow the RE IP procedure in the admin guide, which requires a small downtime window.
Past that, I'm curious, what's the real driver here? Is there a technical or business requirement driving this?
Asking as, honestly, the vast, vast majority of our customers do not do this, at least in this manner. The majority of the isolation/segmentation requests we get are for narrowing the environemnt to a separate set of physical switches, not just a VLAN on the same switch
Reading the doco on weighting seems to suggest that would work? Though I believe I would need to change the cvms ip manually, and there doesnt seem any doco for that.
