vSAN witness 7.0U1d in VCF 4.2.1

I've noticed that VCF 4.2.1 makes use of ESXi 7.0U1d and vSAN is no longer listed as a line item on the BOM because it ties to the ESXi version.  However, only the witness appliance is available in 7.0U2, 7.0U1c, etc.

Is the desired outcome to deploy the witness as 7.0U1c and then upgrade or remain at the 7.0U1c witness that is available for download?

You can use the 7.0 Update 1c  witness appliance. https://docs.vmware.com/en/VMware-Validated-Design/6.2/rn/vmware-validated-design-62-release-notes.h...

Thanks I hadn't looked over at the VVD BOM in a while.  Seems like specifically this component should be the same in both places.

ideally your Witness node should be in the same build version of your Site Nodes . its a VSAN think not VCF or else you might have issue on VSAN . So i would say you can deploy the Witness node with 7.0 Update 1d as per VCF 4.2.1 , you will be in the BOM . 

Going outside of BOM is not support. never tested u get any issues. 

Thanks & Regards,

Right, I agree with all that, but there isn't a witness available to download for U1d (only U1c is available).  So it sounds like the intent is to deploy U1c and then upgrade to U1d.  It's just not spelled out in the VCF BOM, instead it's in the VVD BOM as others have pointed out (assumedly because multi-az is considered a solution and is thus in the "VVD" documentation).
