Hi All,

We have scheduled to perform a Nutanix Cluster upgrade.

Existing Setup:

3xDell XC730 XD-12 running on AHV 20170830.453 / AOS(5.15.3). This cluster is hosting around 50 VMs.

Upgrade to:
4* NX 8235 -G7-4215R -CM

Is it possible to add the 4*NX to existing cluster and then remove 3xDell XC servers. We are trying to achieve minimum downtime here without major outage.

Per Nutanix documentation https://portal.nutanix.com/page/documents/details/?targetId=Hardware-Admin-Ref-AOS-v5_17%3Ahar-product-mixing-restrictions-r.html , it seems mixing hardware isn't feasible. Could you please confirm if there is any work around possible?

Regards,

It is completely unsupported to mix hardware of different vendors in the same cluster. You will need to build a new cluster out of the 4 NX nodes and then use a protection domain to migrate the VMs. The downtime eventually will be very short with the duration of just VMs restart.
