The following instructions have helped other people upgrade to -current

[Remember to make yourself a new config (not config.old) kernel config file.]
[Make sure you have COMPAT_10 as part of your kernel config options.]
[This assumes that the -current source is in /usr/src]

(cd /usr/src/usr.sbin/config ; make && make install && make cleandir)
# if you don't do this, config of your kernel config file will
# fail with errors in files.i386

(cd /usr/src/gnu/usr.bin/gas ; make && make install && make cleandir)
# if you don't do this, you won't be able to build locore.s, with
# errors about cpuid instruction not found

(cd /sys/arch/i386/conf ; config MYKERNEL)
(cd /sys/arch/i386/compile/MYKERNEL ; make depend && make)
# copy  new kernel to /, and boot off it

(cd /usr/src/share/mk ; make install)
# if you don't do this, you'll get errors building gcc, when it
# doesn't know how to make the manual pages (don't know how to make gcc.0)

(cd /usr/src/gnu/usr.bin/gcc2 ; make && make install && make cleandir)

# it was at this stage that I got REALLY fed up with the
# sh: warning: running as root with dot in PATH
(cd /usr/src/bin/sh ; make && make install &&  make cleandir)

# Bernd Wisener says that the ld.so that will be built next will
# work only with libc.so.12.0, not with libc.so.12.3
# His instructions to make a working ld.so follow:
# Do NOT run ldconfig while doing the folowing 5 lines ...
(cd /usr/src/include ; make && make install)
cp -p /usr/libexec/ld.so /usr/libexec/ld.so.good
(cd /usr/src/gnu/usr.bin/ld ; make && make install && make cleandir)
cp -p /usr/libexec/ld.so.good /usr/libexec/ld.so
(cd /usr/src/lib ; make && make install && make cleandir)
# Then build ld.so again ...
(cd /usr/src/gnu/usr.bin/ld ; make && make install && make cleandir)  
# Thanks, Bernd...

# and now back to the beginning and make the world
(cd /usr/src/bin ; make && make install && make cleandir)
(cd /usr/src/sbin ; make && make install && make cleandir)

mkdir /usr/share/doc/usd/13.viref
# otherwise "make install" in /usr/src/usr.bin will fail because
# the destination directory doesn't exist - from Tom Thai

# if you're using the obj directory hierarchy, use
(cd /usr/src/usr.bin/lex ; cp initscan.c obj/scan.c)
# otherwise (i.e. no obj directory hierarchy)
(cd /usr/src/usr.bin/lex ; cp initscan.c scan.c)
# if you don't, then lex won't be built

(cd /usr/src/usr.bin ; make && make install && make cleandir)
(cd /usr/src/usr.sbin ; make && make install && make cleandir)
(cd /usr/src/libexec ; make && make install && make cleandir)
(cd /usr/src/gnu ; make && make install && make cleandir)
(cd /usr/src/share ; make && make install && make cleandir)

mkdir /usr/share/doc/usd/30.rogue /usr/share/doc/usd/31.trek
# otherwise "make install" in /usr/src/games will fail

(cd /usr/src/games ; make && make install && make cleandir)

Cheers,
Alistair
