Thank you for the link. However, I was not interested in the liftover VCF files - since "careful" is pretty meaningless here. It doesn't really matter how careful you are if the file is not generated from BAMs aligned to a true hg38 reference.
Thank you for the suggestion anyway.

This is typically not recommended as it runs the risk of annoying people in both communities.
I thought that ought to integrate the two and make the answers easier to find, no? :)
