create job group for new release
adjust description and link of the parent group if needed
Dump the templates of the previous distribution, change version and import again. E.g.
script/dump_templates --host https://openqa.opensuse.org --group "openSUSE Leap 42.2" --full > leap
Same with staging projects. Afterwards review and adjust accordingly
The staging group may need to be renamed an re-created in order to preserve old results and allow for build numbers to repeat
