SC8 to RHEL8 migration "Transaction test error"

Good afternoon,

following Linux migration page, I would like to migrate my CS8 workstation to RHEL8.
I get this error (full description below)

"Error: Transaction test error:
  file /etc/pki/rpm-gpg/RPM-GPG-KEY-redhat-release from install of redhat-release-666:8.8-0.8.rh8.cern.x86_64 conflicts with file from package containers-common-2:1-51.module_el8+454+d7ef4b8d.x86_64"

I see the section “Troubleshooting a failed migration” at the end of the documentation page, it recommends to remove the package containing this file, would any of you have seen this error and should I do this for this file?

thank you,
Eric
