Upgrading vSAN is a multistage process and you must perform the upgrade in a specific sequence.


The disk format upgrade is optional. If you use a previous disk format version, your vSAN cluster continues to run smoothly . For best results, upgrade the objects to use the latest on-disk format. The latest on-disk format provides the complete feature set of vSAN. To understand the vSAN upgrade process, see About the Virtual SAN Disk Format.
