• Conducting backup of / volume. On backup.qa as root:

rsync -aHP --one-file-system --exclude=/tmp/ --exclude=/lost+found/ openqa.suse.de:/ /home/backup/osd/root-complete/

• Then first setting prios for repos and checking that there are no important updates pending:

zypper mr -p 105 8
zypper mr -p 90 4
zypper mr -p 95 3

• mariadb wants to be installed, does not seem to make sense. With reviewing /var/log/zypp/history I could find out that mariadb-errormessages is installed, uninstalled it. Still wants to be installed, don't know how to find out "why does package want to be installed"

• Checking all config files already needing an update:

for i in $(find /etc/ -name '*.rpm*') ; do vimdiff ${i%.rpm*} $i; done
find /etc/ -name '*.rpm*' | grep -v 'rpm-utils' | xargs rm

• Correcting a typo found in https://build.opensuse.org/package/view_file/openSUSE:Factory/sudo/sudo-sudoers.patch?expand=1 -> build.opensuse.org/request/show/724360

• Created Engineering Infrastructure ticket https://infra.nue.suse.com/SelfService/Display.html?id=145106&results=0e2ec60caaef402ae9ccf827f89d7948 to support on potential boot-up problems

• Removed unneeded packages

zypper rm $(zypper packages --unneeded| awk '/^i/{ print $5 }' ORS=" ")

in a loop until the list was turning out empty. Afterwards deleted not currently booted kernels

• Deleted some data from different /home/* folders and sent email to each user when I deleted data. All data is still available in the backup

• Encountered potential problems packages on upgrade, conducting test upgrade in chroot:

rsync -aHP backup.qa:/home/backup/osd/root-complete/ poo54137_test_upgrade_of_osd/root-complete/ --exclude=home/*
for i in sys proc dev dev/shm dev/pts run ; do mount -o bind /$i poo54137_test_upgrade_of_osd/root-complete/$i; done
chroot /abuild/poo54137_test_upgrade_of_osd/root-complete/
zypper rl postfix
zypper in postfix
mkdir /tmp
rm /var/log
mkdir -p /var/log
zypper dup
zypper rm $(zypper packages --unneeded| awk '/^i/{ print $5 }' ORS=" ")
zypper dup

this resulted seemingly in a loop. zypper dup wants to install "SUSEConnect drm-kmp-default ft2demos rollback-helper" but they end up as being reported as "unneeded", maybe a limitation of the chroot experimentation environment or maybe solvable by enough reruns (see above for reason of looping).

Then conducted upgrade with

cd /etc/zypp/repos.d/
sed -i -e 's/42\.3/$releasever/g' *
sed -i -e 's@suse/@@' *
zypper --releasever=15.1 ref
zypper -n --releasever=15.1 dup --auto-agree-with-licenses --replacefiles --download-in-advance

turning out everything good.

EDIT: Understood now what happened on OSD itself: I tried to change repo files but salt recipes put in back a version without $releasever hence zypper tried to install or rather keep packages from them resulting in unresolvable dependencies when trying to upgrade -> https://gitlab.suse.de/openqa/salt-states-openqa/merge_requests/133

• Plan or to revisit: Update the repos so that we can upgrade with "$releasever":

cd /etc/zypp/repos.d/
sed -i -e 's/42\.3/$releasever/g' *
zypper --releasever=15.1 ref
sudo -u geekotest /opt/openqa-scripts/dump-psql && zypper -n --releasever=15.1 dup --auto-agree-with-licenses --replacefiles --download-in-advance
rpmconfigcheck 
for i in $(cat /var/adm/rpmconfigcheck) ; do vimdiff ${i%.rpm*} $i ; done
for i in $(cat /var/adm/rpmconfigcheck) ; do rm $i ; done
reboot

merged, everything else looks fine. Considered done.
