This section describes how to upgrade vSAN from U3 to EP15.
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. For more information, see About the Virtual SAN Disk Format.
Procedure
