I tested like you said.

I removed --useexisting from logvol root, but then it complains about
home etc.. So I removed --usexisting and --noformat from all logvol
definitions and it actually began installing, but failed with

error: logical volume "swap" already exists in volume group "rhel_rhellv01"

With --useexisting the LVs are not  found and it does not even begin
the installation.

Without --useexisting it begins installation but can't create the LVs
because they already exist. This does not surprise me. And when I look
on the console the LVs are not activated, but I can do vgchange -ay.
However, the old /boot is destroyed at that point and the old system
won't boot anymore and I have to install/repair again.

I'm not sure how to proceed. Maybe I try Fedora to see if it only
fails with RHEL 8 (as I said it does work with RHEL 7)
