If you have kept home directories and custom non-standard-distros 
applications and support files on other than the
system partitions (or the equivalent if you are using a disk with too 
much capacity to use the older partition methods), e.g., /home, /opt, 
/usr/local, and the like, then
simply use the install media to install into typical systems partitions 
(e.g., /usr , /boot , ... ) and you will be operational.  If you are 
statically configuring the NIC/WNIC and Internat access configuration 
files (e.g., the actual IPv4, IPv6 address configuration information for 
the NIC/s, etc.), then simply installing into the other partitions as 
required should result in a working system.  Note that I use gparted to 
convert the overwritten partitions to a "newer" format (such as XFS), 
Upon reboot, all of the older applications and previous home directories 
should be present.  Note also that if the older applications require 
specific .so files or utilities (older loader, etc.), these must be 
obtained and installed .
