Upgrading From the Solaris 8 Operating Environment

If you are already running the Solaris 8 operating environment and have installed individual patches, upgrading to a Solaris 8 Update release causes the following:

• Any patches supplied as part of the Solaris 8 Update release are reapplied to your system. You cannot back out these patches.

• Any patches previously installed on your system that are not included in the Solaris 8 Update release are removed.

To see a list of patches that are removed, use the Patch Analyzer as described in the following section.

Analyzing the Patches

The Patch Analyzer performs an analysis on your system to determine which (if any) patches will be removed by upgrading to the Solaris 8 Update release. The Patch Analyzer is available in the following formats.

• If you are using the Solaris Web Start 3.0 installation method on the Solaris 8 Installation CD to upgrade, refer to "Using the Patch Analyzer With a Solaris Web Start 3.0 Upgrade".

• If you are using the Interactive Installation method to upgrade, select Analyze on the Patch Analysis dialog box to perform the analysis. For detailed instructions, see "Upgrading From Solaris 8 or a Solaris 8 Update: the Patch Analyzer" in Solaris 8 Advanced Installation Guide.

• If you are using a custom JumpStart^TM installation to upgrade, run the analyze_patches script to perform the analysis. For detailed instructions, see "Upgrading From Solaris 8 or a Solaris 8 Update: the Patch Analyzer" in Solaris 8 Advanced Installation Guide.

Using the Patch Analyzer With a Solaris Web Start 3.0 Upgrade

This section supplements "Upgrading a System" in Solaris 8 (SPARC Platform Edition) Installation Guide and "Upgrading a System" in Solaris 8 (Intel Platform Edition) Installation Guide.

The Solaris Web Start 3.0 installation method gives you the option to use the Patch Analyzer to analyze the patches on your system. After you choose Upgrade, the Patch Analyzer dialog box appears.

1. In the Patch Analyzer dialog box, choose Yes and click Next.

   The Patch Analyzer reviews the system patches.

   The Patch Analyzer Summary dialog box displays the total number of patches that will be removed, downgraded, accumulated, or made obsolete by other patches.

2. To see the specific patches that might be removed, downgraded, accumulated, or obsoleted by other patches, click the Details button(s).

3. Decide if the patch replacements and deletions are acceptable.

   • If the patch replacements and deletions by the Solaris 8 Update release are acceptable, click Next to complete the upgrade.

   • If the patch replacements and deletions by the Solaris 8 Update release are not acceptable, click Exit to terminate the upgrade. You can use the Solaris 8 Maintenance Update and the Solaris 8 Maintenance Update Installation Guide to install the patches on your Solaris 8 system.
