src upgrade from 4.11-p16 to 5.4 possible?

[Derek Ragona]

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

         -Derek
