My original question was
How can I tell why this system insists on an initial
install? It should be upgradable!
Many thanks to those who replied.
The best answer was contained in the INFODOC 17987 which I have
included below.

How can I test my current system to verify it can be upgraded to Solaris 2.6?
To test an operating system's upgradeability to Solaris 2.6,
a utility called pfinstall which performs a 'dry run' install can
be used. The pfinstall command was first available with Solaris 2.6.
pfinstall can be used to prescreen an OS for potential errors that could
prevent an upgrade. Some examples of errors that pfinstall can
capture are: file systems with insufficient space, errors parsing the
/etc/vfstab file and required files missing from the /var/sadm directory.
Shutdown the system.
>From the OBP (Open Boot Prom), boot the cdrom to single user. The
CD must be a Solaris 2.6 CD.
OK boot cdrom -s
When the system is booted, create the test profile:
# csh
# setenv TERM sun
# vi /tmp/prof
Add the following two lines.
install_type upgrade
root_device /dev/dsk/c0t3d0s0 <--This may need to be changed depending
on system
Save file
run pfinstall program
/usr/sbin/install.d/pfinstall -D /tmp/prof | more
Program will run a dry run of the upgrade procedure and give you
any problems which will prevent the system from being upgrade.
Some files which are REQUIRED to be inplace are
/var/sadm/install/contents
/var/sadm/system/admin/.clustertoc
/var/sadm/system/admin/CLUSTER
/var/sadm/system/admin/INST_RELEASE
If thes files are not in place you will get a error message of...
ERROR: Failure loading local environment
Which indicates one of the above referenced files is missing.
An error message of...Error: Fatal Signal recieved (11)
can mean one of the above referenced files is empty or corrupted.
man pfinstall has additional information. Including the following warning:
WARNING:
If the -d or -D option is not specified, pfinstall may per-
form an actual installation on the system by using the
specified profile, and the data on the system may be
overwritten.
pfinstall will exit with the following message:
Test run complete. Exist status X
where X is:
EXIT STATUS
0 Successful (system rebooted).
1 Successful (system not rebooted).
2 An error occurred.
pfinstall may report more than one Exit Status! It may report an
Exit Status=2 for a vfstab file error and then proceed to the next
section and report an Exit Status=0.
pfinstall output can be lengthy. Data can be captured by using the
script command. For example:
#script /tmp/pfinstall_out
#/usr/sbin/install.d/pfinstall -D /tmp/prof | more
#^D <--When pfinstall has completed, input Control+D to
exit the script program
#more /tmp/pfinstall.out
More info on the upgrade process is found in the Solaris 2.6 Advance
Installation Guide (Sun Part Number 802-5740)
