I recently did this exact operation. It went fine for me on my second
try. The first one I determined didn't go well as I didn't have the system
up to date first. So on my second attempt I made sure my 4.11 system was
up to date, and did a complete buildworld, buildkernel, etc. Once I was
sure it was completely up to date on 4.11, I:
Saved my kernel config file to:
/usr/oldkernels/
rm -rf /usr/src
rm -rf /usr/ports
I changed my cvsup tag and pulled new source. Then I meticulously followed
the instructions in /etc/src/UPDATING. Read those instructions, be sure to
update your /etc/make.conf file for the right CPU.
I did need to create a new kernel configuration file starting with GENERIC
and boot.hints from my old 4.11 kernel configuration file.
All went well except one library didn't get put in place when I did the
installworld. It was built but just not in place, so I saw an error when I
booted the system, and moved it manually.
The library that didn't get moved was:
libc.so.4
I did add:
COMPAT4X= yes
to my make.conf file and
options COMPAT_FREEBSD4 # Compatible with FreeBSD4
to my kernel config file, but still had to make sasl2 and sendmail for
sasl2. Otherwise the ports I had seemed to mostly work. But you might
want to do a:
portupgrade -a

Hello all,
I am running a set of 5 FreeBSD 4.11 p16 servers here at the library.
For various reasons we are unable to 'get new drives' and install FreeBSD
5/6 and then migrate userland data to a new drive.
I have been able to get my hands on a test box from someone to test src
upgrading from 4.11 to something more current like 5.x and then updating
from there.
My standard running machines are Dual 933 Intel machines, 1G ram, scsi
drives.. etc
This test box is an AMD Mobile Sempron 2600+ w/ 512M ram, 80G ide drives.
http://www.freebsd.org/releases/5.4R/migration-guide.html is the guide
that I am following.. and I have done what I think are the right steps..
and I am getting a crash/failure in a most unusual place.
Stop in /usr/src/usr.sbin/pcvt/vgaio.
*** Error code 1

The strange thing is this:
CPU: Mobile AMD Sempron(tm) Processor 2600+ (799.92-MHz 686-class CPU)
this is what dmesg tells me about this cpu.. again this is under 4.11
So I am wondering if these things are related, and if I try this on an
Intel cpu will I still have this issue?
As my cvsup to RELENG_5_4 and then make buildworld fails at this point.
I have script'd the make buildworld which is a 9M text file, and it
compresses down to a ~500k bz/gz file if anyone is interested in it.
I have tried in single user mode as well again no difference. I have
tried make -j4 buildworld (only gets there faster.. )
Thanks in advance any help is greatly appreciated.
(I'm going to try 5.3 and then if that doesn't work then I'll try 5.2.1)
