Environment

vCenter 8.x

Cause

• VLCM will not downgrade host components. 

 

Resolution

• Edit the cluster image to include the same version of HBR already configured on ESXi.
• Remove the VIB from the host manually using the command <esxcli software vib remove -n vmware-hbr-agent>
  • Then re-apply the cluster image. 
• OR just remove the HBR vib from both the host and cluster image if it is not utilized.
