FC3 => FC5 upgrade... possible?

[Philip Prindeville]

I have a system that was installed as FC3, and has been extensively
reconfigured (added outside repos, etc) and did some source-level
builds and installs.

I'm hoping to find a path to upgrade to FC5, rather than having to
note all my config changes, save all my data, install, reconfigure,
and then restore my data.

Can this be done?

Thanks,

-Philip
