Given the complexity of your existing config, then I would think that
Live Upgrade is a lower risk path than experimenting with 8/03 as the
base for SRSS3.(1).

Live upgrade is documented in the Solaris Installation Guide, chapters
29 - 36:

http://docs.sun.com/app/docs/coll/214.19?

In this case the url refers to the 9 12/03 collection but you should
probably go for the latest 9/05 (or dare I say it, Solaris 10?)

The main pre-requisite is that the system must have a spare disk which
can be booted, or spare space and partitions on an existing disk to be
the target for the upgrade. LU copies the existing environment to spare
disk space and then provides the means to do a Solaris upgrade install
on that copy while the system is in production. It also manages which
boot environment is current.

Once you successfully do a live upgrade, you could boot from the new
environment and verify that your apps work correctly. If that's the
case, then you could proceed to upgrade SRSS.

This won't eliminate downtime, but it will minimise it, and provide a
fallback which can be invoked immediately.
