 Notes for upgrading CentOS7 to CentOS8 in place:
+https://www.alessandronuccio.it/2020/10/21/upgrade-centos-7-to-centos-8/
+  * 'rpm -e `rpm -q kernel`' would fail, try to erase current kernel
+  * 'dnf --releasever=8 --allowerasing --setopt=deltarpm=false distro-sync' would also fail, trying to remove the current kernel
+  * Got stuck into kernel dependency issues
+  * Aborted this track

+  * Had to follow instructions very carefully and ensure to follow every step
+  * Finally got to a point I could not continue
+Tried this but failed:
+dnf upgrade http://mirror.centos.org/centos/8/BaseOS/x86_64/os/Packages/{centos-release-8.1-1.1911.0.8.el8.x86_64.rpm,centos-gpg-keys-8.1-1.1911.0.8.el8.noarch.rpm,centos-repos-8.1-1.1911.0.8.el8.x86_64.rpm}
+Then tried this:
+dnf upgrade http://mirror.centos.org/centos/8/BaseOS/x86_64/os/Packages/{centos-linux-release-8.3-1.2011.el8.noarch.rpm,centos-gpg-keys-8-2.el8.noarch.rpm,centos-linux-repos-8-2.el8.noarch.rpm}

+No match for argument: /var/cache/dnf/commandline-5fda33494c9fb882/packages/centos-linux-repos-8-2.el8.noarch.rpm
+Error: No packages marked for upgrade.
+Then did this:
+dnf install http://mirror.centos.org/centos/8/BaseOS/x86_64/os/Packages/{centos-linux-release-8.3-1.2011.el8.noarch.rpm,centos-gpg-keys-8-2.el8.noarch.rpm,centos-linux-repos-8-2.el8.noarch.rpm}
+Seemed to work.
+Ran dnf --releasever=8 --allowerasing --setopt=deltarpm=false distro-sync
+but got this:

+To diagnose the problem, try running: 'rpm -Va --nofiles --nodigest'.
+You probably have corrupted RPMDB, running 'rpm --rebuilddb' might fix the issue.
+The downloaded packages were saved in cache until the next successful transaction.
+You can remove cached packages by executing 'dnf clean packages'.
+Ran: dnf remove vdo fcoe-utils
+rpm -Va --nofiles --nodigest
+rpm --rebuilddb
+Can't continue.
