Hello Fabian,

Just an idea from the top of my head (not tested):
1) create and sync Fedora26 channels in Spacewalk server
2) subscribe Fedora25 clients to Fedora26 channels (from webUI via System group)
3) unsubscribe Fedora25 clients from Fedora25 channels 
4) run 'dnf system-upgrade download --releasever=26' (from webUI via
remote commands)

> I think the procedure above, if existing, should work also for
> upgrades F26 to F27.
