There are multiple strategies available when upgrading to the Solaris 10 OS.
Phase 2: Planning
Deploying new Sun platforms with the Solaris 10 release can help to consolidate applications, frequently eliminating several existing, less powerful servers and their associated complexity and support costs.
In contrast, upgrading to the Solaris 10 OS on existing compatible systems (an "upgrade-in-place" strategy) can often result in better application performance because of enhanced run-time binaries and libraries, improved threading models, and new features.
On SPARC platforms, rather than running applications natively on the Solaris 10 OS, it's also possible to upgrade incrementally using Solaris 8 or 9 Containers on the Solaris 10 release. See the BigAdmin article Using Solaris Containers to Host Solaris 8 and 9 Environments on the Solaris 10 OS for more info. You can also use Solaris Containers for Linux Applications on the Solaris 10 release in a similar manner as explained on the Solaris Containers for Linux Applications web site.
Whatever the approach, whether you upgrade in place or upgrade on a new system, careful planning can help make the upgrade process go more smoothly. Solaris 10 10/09 Installation Guide: Planning for Installation and Upgrade provides planning information for any Solaris installation or upgrade.
In addition Chapter 7, Solaris Live Upgrade (Planning) of Solaris 10 Installation Guide: Solaris Live Upgrade and Upgrade Planning can help you understand the system requirements for using Solaris Live Upgrade on the Solaris 8, 9, or 10 OS. Solaris Live Upgrade can help facilitate the upgrade process, reduce downtime associated with an upgrade, and provide a fallback path.
Use the following resources to assess the feasibility of a Solaris 10 OS upgrade, determine the optimal upgrade strategy, and learn about available upgrade resources and services.
