Upgrade 6.1 to 7.1 remotely?

[Robert Fitzpatrick]

I have a remote system with no access to boot info. I can get someone to
reset, look at screen, etc. The server is 6.1-RELEASE-p15 and wondering
if there is a path to upgrade to 7.1 remotely. Would it be possible to
do something like this for getting the box to 6.4...

And then another freebsd-update to 7.1? Seems that box will not let me
portupgrade clamav anymore due to a change from 6.1 :(

../libclamav/.libs/libclamav.so: undefined reference to `gethostbyname_r'
*** Error code 1
