I got an error while upgrade ESXi host from ESXi 5.5 to ESXi 6.5 . The upgrade process failed with the error “Conflicting_vibs Error” which explained at the picture I added.
At this KB I explained how to fix this error.
Error: <CONFGLICTING_VIBS ERROR: Vibs on the host are conflicting with vibs in metadata.Remove the conflicting vibs or use image builder to create a custom ISO providing newer version of the conflicting vibs.
