1 Developing an Upgrade Strategy

Before you begin an upgrade from Oracle Application Server 10g to Oracle Fusion Middleware 11g, there are important tasks you should perform in preparation for the upgrade.

Use the following tasks to ensure that your upgrade has as little impact as possible on your day-to-day operations:

1.1 Task 1: Understand the Differences Between Oracle Application Server 10g and Oracle Fusion Middleware 11g

Before you begin planning your upgrade to Oracle Fusion Middleware, you should be familiar with the differences between Oracle Application Server 10g and Oracle Fusion Middleware 11g.

Refer to Chapter 2, "Introduction to Oracle Fusion Middleware for 10g Users" for an introduction to architecture, directory structure, terminology, and installation and configuration tools of Oracle Fusion Middleware 11g.

1.2 Task 2: Understand the Upgrade Starting Points

Refer to the following sections for more information about what Oracle Application Server versions are supported for upgrading to Oracle Fusion Middleware 11g:

1.2.1 Upgrade Versus Patching

In the Oracle Fusion Middleware documentation, upgrade refers to the process you use to upgrade from a previous major or minor release to another. Specifically, this guide is for upgrading from Oracle Application Server 10g to Oracle Fusion Middleware 11g.

If you are already running Oracle Fusion Middleware 11g and you want to update your system to the latest patch set (for example, Oracle Fusion Middleware 11g Release 1 (11.1.1.7.0), then refer to the Oracle Fusion Middleware Patching Guide for complete instructions on applying the latest Oracle Fusion Middleware 11g patch set.

1.2.2 What is an Upgrade Starting Point?

An upgrade starting point is a specific version of Oracle Application Server that you must be running in order to upgrade to Oracle Fusion Middleware 11g. If you are not running a version of Oracle Application Server that is a supported upgrade starting point, then you must first upgrade to a supported starting point using documentation from a previous release.

Documentation for previous releases is available on the Oracle Technology Network (OTN):

1.3 Task 3: Get Familiar With the Installation and Upgrade Tools

The procedures and tools you use to install and configure the Oracle Fusion Middleware components are very different from the ones you used to install and configure Oracle Application Server 10g.

Refer to Section 2.2, "Oracle Fusion Middleware Installation and Configuration Tools" for an overview of the installation and configuration tools required to set up a complete Oracle Fusion Middleware 11g environment.

1.4 Task 4: Develop a Backup Strategy for Upgrade

Before you begin upgrading your Oracle Application Server 10g environment, be sure you have backed up system-critical files.

Refer to Chapter 4, "Backup Strategies for Upgrade" for specific information on making sure all the various components of your environment can be restored in the event of a failed upgrade.

1.5 Task 5: Understand Your Certification, Compatibility, and Interoperability Requirements

Before you begin upgrading your Oracle Application Server 10g environment, consider the following:

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.

1.6 Task 6: Review the System Requirements for Upgrade

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:

1.6.1 Locating System Requirements Information Before Upgrade

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.

1.6.2 A Note About User Accounts When Upgrading to Oracle Fusion Middleware 11g

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.

1.7 Task 7: Understand the Basic Rules and Restrictions of Upgrade

Before you start the upgrade process you should understand some basic rules and restrictions.

Specifically, do not attempt to perform an Oracle Fusion Middleware 11g upgrade while also performing an unrelated migration of your software from one platform to another.

For example, do not perform an upgrade while simultaneously doing any of the following:

  • Moving from one operating system (such as Windows) to another (such as Linux)

  • Moving from one database type (such as Oracle) to another (such as Microsoft)

  • Moving from one hardware platform (such as SPARC) to another (such as Intel)

  • Moving from a 32-bit operating system to a 64-bit operating system

If you plan to perform any of these or similar actions, then you must do them separately and independently of the Oracle Fusion Middleware 11g upgrade process.

For a more specific example, if you plan to move from a 32-bit to a 64-bit operating system, then you must either:

  • Upgrade your Oracle Application Server 10g software to Oracle Fusion Middleware 11g, validate the upgrade, ensure that the upgrade was successful, and only then migrate your software to a 64-bit operating system.

    OR

  • Migrate your 32-bit environment to a 64-bit software environment, validate the migration to ensure all your Oracle Application Server 10g software is working properly, and only then perform the upgrade to Oracle Fusion Middleware 11g.

1.8 Task 8: Locate the Required Upgrade Documentation

The Oracle Fusion Middleware documentation library provides upgrade documentation for each of the Oracle Fusion Middleware product suites.

Depending upon the 10g Release 2 (10.1.2) or 10g Release 3 (10.1.3) environment you are upgrading, use Table 1-2 to determine which guide to use when upgrading your Oracle Application Server components to Oracle Fusion Middleware.
