Hi All,

Is tehre a way to upgrade FC36 --> FC37 using the iso?

Nope. Upgrade support in the installer was done away with many releases ago. The only working path is dnf system-upgrade.

If there are multiple machines to upgrade there are ways to avoid having to redownloadable the same thing, repeatedly. After dnf system-upgrade download:

rsync -avH --link-dest=../system-upgrade \
  /var/lib/dnf/system-upgrade/. /var/lib/dnf/system-upgrade.backup

This makes a very quick copy of /var/lib/dnf/system-upgrade, which gets automatically deleted during the upgrade. After the upgrade, copy it to the next machine's /var/lib/dnf/system-upgrade directory, then run system- upgrade download again, on it, to pick up any additional packages the 2nd machine needs, and set up the upgrade. Make a backup copy of the refreshed directory on that machine, the same way. Lather, rinse, repeat.
