Sun Java System Application Server 9.1 Upgrade and Migration Guide

Binary and Remote Upgrades

The tool does not update the runtime binaries of the server. The Upgrade tool upgrades the configuration information and deployed applications of a previously installed server. You need to use the Application Server Installer to install the server binary packages. The first step in the upgrade process is to use the Installer to install the target server binaries.

You cannot perform an upgrade if the source and target server file systems, specifically the domain root file system, are not accessible from the same machine. Currently, most of the upgrade is file based. To perform the upgrade, the user who runs the upgrade needs to have Read permissions for the source and target directories and Write permission for the target directory.
