Hello,
I followed some instructions I found in https://www.ovirt.org/documentation/upgrade_guide/ and https://www.ovirt.org/download/install_on_rhel.html by doing the following:

  883  subscription-manager repos --enable rhel-8-for-x86_64-baseos-rpms
  884  subscription-manager repos --enable rhel-8-for-x86_64-appstream-rpms
  885  subscription-manager repos --enable codeready-builder-for-rhel-8-x86_64-rpms
  886  rpm -i --justdb --nodeps --force "http://mirror.centos.org/centos/8-stream/BaseOS/$(rpm --eval '%_arch')/os/Packages/centos-stream-release-8.6-1.el8.noarch.rpm"
  887  cat >/etc/yum.repos.d/CentOS-Stream-Extras.repo <<'EOF'
  888  [cs8-extras]
  889  name=CentOS Stream $releasever - Extras
  890  mirrorlist=http://mirrorlist.centos.org/?release=8-stream&arch=$basearch&repo=extras&infra=$infra
  891  #baseurl=http://mirror.centos.org/$contentdir/8-stream/extras/$basearch/os/
  892  gpgcheck=1
  893  enabled=1
  894  gpgkey=https://www.centos.org/keys/RPM-GPG-KEY-CentOS-Official
  895  EOF
  896  cat >/etc/yum.repos.d/CentOS-Stream-Extras-common.repo <<'EOF'
  897  [cs8-extras-common]
  898  name=CentOS Stream $releasever - Extras common packages
  899  mirrorlist=http://mirrorlist.centos.org/?release=8-stream&arch=$basearch&repo=extras-extras-common
  900  #baseurl=http://mirror.centos.org/$contentdir/8-stream/extras/$basearch/extras-common/
  901  gpgcheck=1
  902  enabled=1
  903  gpgkey=https://www.centos.org/keys/RPM-GPG-KEY-CentOS-SIG-Extras
  904  EOF
  905  echo "8-stream" > /etc/yum/vars/stream
  906  dnf distro-sync --nobest
  907  reboot
  908  dnf install centos-release-ovirt45
  909  dnf install centos-release-ovirt45 --enablerepo=extras

But now, yum update isn't working because its trying to install centos-stream-release 8.6.1 over redhat-release-8.6.

Surely I shouldn't install CentOS stream release over RHEL release, should I?
See below:

[root@phys1 dwhite]# cat /etc/redhat-release
Red Hat Enterprise Linux release 8.5 (Ootpa)
[root@phys1 dwhite]# yum update
Updating Subscription Management repositories.

Error:
 Problem: installed package centos-stream-release-8.6-1.el8.noarch obsoletes redhat-release < 9 provided by redhat-release-8.6-0.1.el8.x86_64
  - cannot install the best update candidate for package redhat-release-8.5-0.8.el8.x86_64
  - problem with installed package centos-stream-release-8.6-1.el8.noarch
(try to add '--skip-broken' to skip uninstallable packages or '--nobest' to use not only best candidate packages)
