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.
