This is guide, howto upgrade Fedora 15 to Fedora 16 with Preupgrade. Preupgrade download needed packages from the server, set up everything ready and then reboot to Anaconda installer and after package installation it boots to the new system. It’s important backup your important files before upgrading.
If the aim is to update older versions of Fedora to Fedora 16, then each version have to be upgraded step by step:
Upgrade Fedora 12 to Fedora 13 with Preupgrade >>
Upgrade Fedora 13 to Fedora 14 with Preupgrade >>
Upgrade Fedora 14 to Fedora 15 with Preupgrade >>
From Fedora 12 to Fedora 13 guide describe Preupgrade command line method. This guide works also with from Fedora 13 to Fedora 14 upgrade, from Fedora 14 to Fedora 15 upgrade and from Fedora 15 to Fedora 16 upgrade.
If the Fedora version is older than Fedora 12 then I recommend Fedora 16 clean install. Also in other situations, a clean install may be sensible.
