You've gotten some good advice about the steps necessary, but not the
advice that you'll spend a lot less time if you do a new install from
scratch.

There have been massive changes since 4.9 (released 10/29/2003),
including: heavy rework of the kernel and networking stack to work
properly on SMP; inclusion of power management; a total rewrite of the
wireless subsystem; a large number of new drivers; rework of the sound
system; an entirely new USB system; extensive rework of the ports
infrastructure; many thousands of new ports; replacement of the default
UFS1 by UFS2; two reworks of the ata architecture; the devd system;
several different revisions of the compiler; and, well, really, thousands
of other changes.

Unless you have local changes to your source, you're going to have a
great deal less heartbreak just to start from scratch.
