With SXCE EOL coming up fast and the AI not quite up to speed (for this instance at any rate), I've cobbled together and carried out a migration of a Sun e220r sparc box from SXCE.

I used quite abit from Edward Pilatowicz's blog and also Alex Eremin's blog . I altered/diverged to suit my needs as well due to things changing rapidly in OpenSolaris.

I built IPS from the gate, more details on IPS and the mercurial url here: http://opensolaris.org/os/project/pkg/ . With that installed proceeded to create an new root pool on a separate disk.

I utilized the following from Edward's blog, where I've diverged/changed I have commented out the original and noted beside my change:

# we're going to do our install in /a
PKG_IMAGE=/a; export PKG_IMAGE

# mount our zpool on /a
mkdir -p $PKG_IMAGE
mount -F zfs rpool/ROOT/opensolaris $PKG_IMAGE
mkdir -p $PKG_IMAGE/opt
mount -F zfs rpool/ROOT/opensolaris/opt $PKG_IMAGE/opt

# create the basic opensolaris install image.
#pkg image-create -F -a opensolaris.org=http://pkg.opensolaris.org $PKG_IMAGE
pkg image-create -f -F -a opensolaris.org=http://pkg.opensolaris.org/dev $PKG_IMAGE # Sparc requires the dev repos
#pkg refresh
pkg -R $PKG_IMAGE refresh --full # We're not clobbering our original or changing it so the next few are mine too
pkg -R $PKG_IMAGE install entire
pkg -R $PKG_IMAGE install SUNWcsd SUNWcs
pkg -R $PKG_IMAGE install babel_install

# seed the initial smf repository
cp $PKG_IMAGE/lib/svc/seed/global.db $PKG_IMAGE/etc/svc/repository.db
chmod 0600 $PKG_IMAGE/etc/svc/repository.db
chown root:sys $PKG_IMAGE/etc/svc/repository.db

# setup smf profiles
ln -s ns_files.xml $PKG_IMAGE/var/svc/profile/name_service.xml
ln -s generic_limited_net.xml $PKG_IMAGE/var/svc/profile/generic.xml
ln -s inetd_generic.xml $PKG_IMAGE/var/svc/profile/inetd_services.xml
ln -s platform_none.xml $PKG_IMAGE/var/svc/profile/platform.xml

After that I finished with:

echo "rpool/ROOT/opensolaris  -  /  zfs  -  no  -" >> $PKG_IMAGE/etc/vfstab

echo "rpool/ROOT/opensolaris/opt  -  /opt  zfs  -  yes  -" >> $PKG_IMAGE/etc/vfstab

devfsadm -r $PKG_IMAGE

bootadm update-archive -R $PKG_IMAGE

installboot -F zfs /platform/$(uname -i)/lib/fs/zfs/bootblk /dev/rdsk/c0t0d0s0

 Copying relevant networking, passwd, ssh keys, etc. files from the running SXCE system to $PKG_IMAGE, I successfully booted to my OpenSolaris install and tweaked from there.
