To use preupgrade I don't think that's as strict a requirement.

preupgrade does what it does by using yum and it's metadata to figure
out what to download. It sets up a repo for anaconda and then sets up
your system to boot into the installer.

Now, preupgrade does do a test transaction, to look for hang ups to
doing the install. That would be the one place where it might get cranky
about the lack of sha256 support in rpm.
