Note that potential issues can be avoided by making sure you have applied the latest Oracle Application Server 10g patch sets, and that you have reviewed the list of recommended patches that are designed to help you avoid any problems during upgrade.
For more information, see the Upgrade chapter of the Release Notes for your platform. For example, if you are using a Linux operating system, refer to "Patches Required to Address Specific Upgrade and Compatibility Requirements" in the Oracle Fusion Middleware Release Notes for Linux x86.
Before performing any installation you should read the system requirements and certification documentation to ensure that your environment meets the minimum installation requirements for the products you are installing.
Refer to the following sections for more information:
For a complete description of the system requirements for installing and upgrading to Oracle Fusion Middleware 11g, see "Review System Requirements and Specifications" in the Oracle Fusion Middleware Installation Planning Guide.
In most cases, when you are upgrading from a previous major release to Oracle Fusion Middleware 11g, you must first install and configure the Oracle Fusion Middleware 11g software before you perform the upgrade.
Note that when you install the Oracle Fusion Middleware 11g software in preparation for upgrade, you should use the same user account that you used to install and configure the Oracle Application Server 10g software. On UNIX operating systems, this will ensure that the proper owner and group is applied to new Oracle Fusion Middleware 11g files and directories.
The Oracle Fusion Middleware documentation library provides upgrade documentation for each of the Oracle Fusion Middleware product suites.
