In our environment we are currently hosting 2 HP Gen9 ESXi servers. Our plan is to purchase a single HP Gen 10 and having a 3 node cluster made out of it.
To start with I want to create a single node (Gen 10) and slowly start moving VM’s from the esx host to that Nutanix host without interrupting the 2 esx servers. So my question here is, How is it possible for me to start with a Single host and start adding hosts to make up a cluster of 3 nodes (1 → Gen10, 2-Gen9)?

In general, it’s not possible to expand a single or two nodes cluster, you will have to destroy and create a new cluster from the 3 nodes (assuming that you already have our AOS on the 3 nodes), after that the expansion will be easy following a few steps in Prism.
The single-node and two-node solutions are supported on the NX-1175S-G5 and NX-1175S-G6 only.
Check out this KB for more information about Single-Node and Two-Node cluster: KB-5943
Let me know if you have any question.
