Hello, I would like to know that if it is possible to upgrade my fedora installation using the latest fedora ISO. I am aware that this was supported by anaconda in the past (until Fedora 17) but I cannot find an alternative now :(

The main reason for using ISO to upgrade is to save data, I have 3 PCs to upgrade and I cannot afford to download the same packages over and over! I have a limited/metered connection.

I am upgrading from Fedora 24 to Fedora 25 if that matters.

Thanks in advance!

Hi, Direct upgrade is not possible. And actually I don't think there's a viable path for it (jumping from one to the next). But, if you're able to format / and /boot (assuming you've separate partitions for /, /boot and /home, atl least) you could easily do a clean install using the Live ISO. If that's the case you just need to create a bootable thumb drive with the corresponding ISO. Cheers

I am guessing that I will lose all of my install packages/programs and their settings, am I right?

Yes, there's no way to keep all the installed programs. The settings (most) should be stored in your local profile so should be OK.

I see... that would be rather messy and would defeat the whole purpose of saving data!

No, this is not a viable upgrade path. I would not expect you to have the same package set as what is available on the image, and the packages on the image are from the stable repository, you're not getting anything from the updates repo.

Instead, set keepcache = True in /etc/dnf/dnf.conf and copy the downloaded packages to your other machines to save download time. For best results, distribute them as a repository instead of individual files.
