As with hardware, software goes EOL (or at least EOS) as well and the
FreeBSD 6.x branch will not be supported by the FreeBSD project beyond
the end of this month.  Whilst you are free to continue using older
code, you will not be able to rely on the FreeBSD project providing
particularly security alerts and fixes.

I would suggest that your testing to date shows that you will not be
able to deploy your new hardware running the same software image as
you currently deploy.  Your new hardware would therefore seem to
provide an ideal opportunity for you to also move to a newer OS (and
still supported) version of FreeBSD.  You could then choose whether to
maintain the older software on the existing deployed base or validate
the newer software on the older hardware and older units as required.
