Product or Component Compatibility
Auto Deploy To ensure compatibility and best performance, when you upgrade to vCenter Server 6.7, use
Auto Deploy to upgrade ESXi hosts to the same version.
vSphere Distributed Virtual
Switch (DVS)
You must upgrade to DVS version 6.0 or later prior to upgrading to vCenter Server 6.7. See
Knowledge Base article KB 52826.
vSphere Network I/O Control DVS version 6.0 or later supports only Network I/O Control version 3. If you are using an earlier
version of Network I/O Control you must upgrade to Network I/O Control version 3. For more
information, see the vSphere Networking documentation.
vSAN Synchronize versions of vCenter Server and ESXi to avoid potential faults because of differences
in the vSAN support in vCenter Server and ESXi. For the best integration between vSAN
components on vCenter Server and ESXi, deploy the latest version of these two vSphere
components. For more information, see the ESXi Installation and Setup, vCenter Server
Installation and Setup, ESXi Upgrade, and vCenter Server Upgrade documentation.
vSAN disk version vSAN has several different on-disk format versions available depending on the version and
upgrade history of the cluster. Some on-disk format versions are transient while others are
intended for long-term production. As certain vSAN features are tied to the on-disk format
version, the format version must be accounted for when determining interoperability. See
Knowledge Base article KB 2145267.
Legacy Fault Tolerance If the vCenter Server inventory contains a VM on which legacy VMware Fault Tolerance (FT) is in
use, upgrade or migration will be blocked until you turn off this feature. For information about
legacy FT, see Knowledge Base article KB 2143127. For information on disabling or turning off
FT, see Knowledge Base article KB 1008026.
