With Fedora, it's just "skipping one version":

System upgrade is only officially supported and tested over 2 releases at most (e.g. from 36 to 38).

"Skipping two versions" would be (e.g.) starting on 35, skipping 36 and 37, and going directly to 38.

You can start on 35, never upgrade to 36, 37, or 38, then upgrade to 38 when 39 comes out before upgrading from 38 to 39. IME doing jumps like this in most distros is difficult, and I prefer sometimes having to upgrade incrementally like this but being able to drop compatibility shims much earlier (assuming I don't need the compat shim for anything else).

In practice I find fedora upgrades even beyond the "supported versions" tend to go pretty smoothly, hell I've even successfully _downgraded_ fedora before, although this usually requires some "screwing around" and removal of packages.

Fedora in-place upgrades

Interestingly, upgrading in-place from Fedora 25 to 32 worked well enough that Qubes OS’s in-place upgrade tool did exactly that in dom0. It probably helped that most Qubes OS users had roughly the same set of packages installed in dom0.
