How Upgrading Works

Using the graphical installer, you can upgrade shared components and some product components. In a graphical installation session, if upgradable product components are detected on your host, the Choose to Upgrade or Install page is displayed. The components that can be upgraded by the installer are listed in the following table, along with explanation on any Solaris zones issues that might apply.

Table 1–1 Upgrade Support Within the Communications Suite Installer

Product Component	Situation Where the Installer Can Upgrade	Solaris Zones Issues
Application Server	Application Server 7.0 bundled with Solaris 9  Application Server 8.0 bundled with Solaris 10  Application Server 8.1.0 installed with Java ES 2005Q1 (release 3)  Application Server 8.1.2 installed with Java ES 2005Q4 (release 4)	Before Application Server can be installed into a non-global sparse-root zone, the bundled version must be removed from the global zone.
HADB	HADB installed with Java ES 2005Q1 (release 3)  HADB installed with Java ES 2005Q4 (release 4)
Message Queue	Message Queue bundled with Solaris 9  Message Queue bundled with Solaris 10  Message Queue installed with Java ES 2005Q1 (release 3)  Message Queue installed with Java ES 2005Q4 (release 4)	Message Queue can only be installed in the global zone, or in a whole root non-global zone.  From the global zone, Message Queue always propagates to non-global zones.
Communications Express		Cannot install UWC in a local, sparse root non–global zone using the installer. Instead, you need to manually add the UWC and Access Manager packages using pkgadd.

If you are not planning to install any of these product components, you can choose Install New Software. If you are going to install any of these components, select Upgrade Existing Software to initiate an upgrade session. After the upgrade session finishes, you can then start a new installation session. This functionality is not supported for a text-based installation.

During installation, you might encounter additional upgrade situations if the installer identifies incompatible versions of product components that cannot be upgraded by the installer. In this case, you will receive messages that certain products components must be removed or manually upgraded before you can continue with installation. Such upgrading for Communications Suite product components is fully documented in the Sun Java Communications Suite 5 Upgrade Guide and for Java ES product components in the Sun Java Enterprise System 2006Q3 Upgrade Guide.

Shared components are upgraded by the installer along with the selected product components. Shared components can also be upgraded in a dedicated installation session that installs only shared components, enabling them to be synchronized to the current release. If you choose to install the Shared Components item, all required shared components for the Communications Suite release are installed or upgraded.

Note –

If the installer is run in a non-global Solaris zone with a sparse root file system, the Shared Component item is not available for selection .
