For such a large jump in versions, it would probably be a good idea to
obtain a new hard drive and do a complete fresh install of FreeBSD from
scratch, install all the necessary packages, copy over data and add any
local configuration to replicate the functionality of the old system.
This has several advantages:
* You will still have the original 8.2 system available to revert back
to in case of problems
* You can adapt the disk partitioning to suit what current FreeBSD
needs, or you change low level things like switching from UFS to ZFS
if desired.
* It takes the pressure off -- you can in principle work on installing
the new system off-line, apply whatever acceptance tests you need
and then only have as much downtime as it takes to swap in the new
drive.
Cheers,
Matthew
