It has been some time since I wrote complex spec files, but
you might be able to do some of the work in the %pre section,
testing $1 to see if you are upgrading (move the cached
files elsewhere), and then in %post move them to the new
locations.  Making it all work right is not at all fun (as I recall).
I suspect that you are not the first package to have this
problem, so there should be a documented method to deal
with this somewhere in the Fedora docs.  Good luck!
