We have a 3 node hyperflex cluster using HX240C-M4SX nonflash nodes which we will be replacing the nodes with HX220C M5 ALL FLASH NODES. I've googled this but haven't really found any information about this topic. Is it as simple as setting EVC and taking the nodes out 1 at a time and adding the new hardware? Anyone done this or can point me to some documented scenarios for this type of replacement? Thanks.
