When upgrading a VMware vSAN cluster to version 6.5, which two tasks must be completed to comply with upgrade requirements and VMware- recommended best practices? (Choose two.)

RVC was VMware's recommended command-line tool for orchestrating vSAN cluster upgrades in vSphere 6.x, as it allowed a controlled rolling upgrade that kept the cluster operational and validated vSAN health at each step.

Using the latest available ESXi image during a vSAN upgrade is a VMware best practice to ensure all known bugs are patched, hardware compatibility is maximized, and the cluster meets the minimum build requirements for vSAN 6.5 features.

While backing up VMs is a general best practice, it is not listed as a specific vSAN upgrade requirement in VMware's official upgrade documentation for this scenario.

'Full data migration' maintenance mode evacuates all data from a host before maintenance, but VMware recommends 'Ensure Accessibility' for vSAN upgrades to balance data safety and performance - using only 'Full data migration' is not a VMware-mandated requirement.
