Overview

In this example, I use Solaris Live Upgrade to upgrade a Solaris 8 2/02 SPARC system to the original Solaris 10 SPARC release.

• Unless you are upgrading Solaris 8 07/01 or earlier, Solaris 7, or Solaris 2.6, you must install the SUNWluu and SUNWlur packages from the version of the Solaris Operating Environment that you are upgrading to.

• Note that Live Upgrade for Solaris 8 to Solaris 10 Update 5 or later is not supported[1].

• I ran into problems upgrading to Solaris 10 Update 4, but it may have been PEBCAK.

For this example:

• c1t0d0 is the Solaris 8 disk.
• c1t1d0 is unused, and has an identical geometry as c1t0d0. It will be used for the Solaris 10 boot environment.
• I use the same partition sizes and file system locations on the new boot environment.

Duplicate partition table

First, I duplicate the partition table from the source disk to the target.

# prtvtoc /dev/rdsk/c1t0d0s2 | fmthard -s - /dev/rdsk/c1t1d0s2

Create Alternate Boot Environment

Next, I create the Alternate Boot Environment.

# lucreate -c Solaris_8 -m /:/dev/dsk/c1t1d0s0:ufs -m /usr:/dev/dsk/c1t1d0s4:ufs -m /var:/dev/dsk/c1t1d0s3:ufs -m /nsr:/dev/dsk/c1t1d0s7:ufs -m  /opt:/dev/dsk/c1t1d0s5:ufs -m -:/dev/dsk/c1t1d0s1:swap -n Solaris_10

Upgrade the Alternate Boot Environment

I have the Solaris 10 SPARC DVD loopback-mounted in /tmp/mnt.

# luupgrade -u -n Solaris_10 -s /tmp/mnt

upgrade or install properly.
INFORMATION: Review the files listed above. Remember that all of the files 
are located on boot environment <Solaris_10>. Before you activate boot 
environment <Solaris_10>, determine if any additional system maintenance 
is required or if additional media of the software distribution must be 
installed.
The Solaris upgrade of the boot environment <Solaris_10> is partially complete.

Activate the Alternate Boot Environment

# luactivate Solaris_10
WARNING: <1> packages failed to install properly on boot environment <Solaris_10>.
INFORMATION: </var/sadm/system/data/upgrade_failed_pkgadds> on boot 
environment <Solaris_10> contains a list of packages that failed to 
upgrade or install properly. Review the file before you reboot the system 
to determine if any additional system maintenance is required.


**********************************************************************

The target boot environment has been activated. It will be used when you 
reboot. NOTE: You MUST NOT USE the reboot, halt, or uadmin commands. You 
MUST USE either the init or the shutdown command when you reboot. If you 
do not use either init or shutdown, the system will not boot using the 
target BE.

**********************************************************************

In case of a failure while booting to the target BE, the following process 
needs to be followed to fallback to the currently working boot environment:

1. Enter the PROM monitor (ok prompt).

2. Change the boot device back to the original boot environment by typing:

    setenv boot-device 
/pci@9,600000/SUNW,qlc@2/fp@0,0/disk@w21000004cf99d73e,0:a

3. Boot to the original boot environment by typing:

     boot
