Hi,

I have performed several live upgrades of FreeBSD before (3.0Stable to =
3.3Stable), and experienced no problems. However, I think there are more =
differences in 3.0Release (basically, that was the first version that =
supported SMP), and was hoping for some feed back. I know that the =
kernel whitched from AOUT to ELF, so I need to install the new boot =
loader. Will the new boot loader still be able to run the old kernel (in =
case there are problems during the upgrade?).
Also, currently the system compiles binaries by default into the ELF =
format, and can run both AOUT and ELF. I am not sure, after the upgrade, =
would the system still be able to execute AOUT binaries (or is there a =
converter, just in case?).
Please, if anyone is aware of any other issues, let me know (config file =
differences, etc). The system is live, and I want to minimize any =
downtime.

Thank you very much in advance,
Anthony
