  actually it's not neccessary to build rpm and all that all that is required is a libzypp with a one-liner patch to change the self conflicts handling (home:oertel:11-mig-12-2) and the rest is pretty much scriptable (already migrated a test-jeos-vm with this method manually).

  remains to all hack it up in a script, including bootloader installation (grub2) and configuration from scratch, but that's pretty trivial. another part will be trashcan rpm that obsoletes all the packages that are not automatically obsoleted.

  ~ro/hackweek/SCRIPT has the current proceedings

  the trashcan rpm is called cleanup, it is pulled in by a "Supplements: glibc", obsoletes the unwanted packages and is removed in another step.

  many migration traps are being found during using this.

  • installed pure-ftpd is removed during zypper dup. install vsftpd and enable in this case
  • sle12 uses ipv6-privacy by default which makes no sense for a server, disable by setting use_tempaddr to 0 in sysctl.conf
  • set "nowaitforswap=yes" in dracut conf to be able to reuse the systems initrd for VMs
  • reconfigure apache, load the "access_compat" module and search for Include statements with wildcards and replace by IncludeOptional
  • mysql socket in my.cnf should not be hardcoded, it is in /var/run/mysql now since /var/lib/mysql has no access rights for "other"
  • add remote syslog server to rsyslog.d/remote.conf
  • remove /etc/mtab and replace by link to /proc/self/mounts
  • configure grub2 and add config for serial console
  • install grub2 to disk
  • sync and reboot
