3 Upgrading to 12c from a Previous Release

This chapter describes the process of upgrading to the Oracle Infrastructure 12c (12.1.3) from a previous Oracle Infrastructure 12c release.

This chapter contains the following topics:

• Section 3.1, "Performing the Required Pre-Upgrade Tasks"

• Section 3.2, "Using the Upgrade Assistant to Upgrade Your 12c Schemas"

• Section 3.3, "Using the Reconfiguration Wizard to Upgrade Your 12c Domain"

• Section 3.4, "Using the Upgrade Assistant to Upgrade Your 12c Configurations"

Caution:

The tasks described in this chapter apply only when you are upgrading from an existing Infrastructure 12c release to the Infrastructure 12c (12.1.3) release. If you are upgrading an 11g environment to 12c (12.1.3), use the procedures documented in Part I, "Upgrading to Oracle Infrastructure 12c (12.1.3) from 11g".

3.1 Performing the Required Pre-Upgrade Tasks

When you upgraded to Infrastructure 12c, you were instructed to complete the pre-upgrade steps in Chapter 2 before starting the upgrade. Review those tasks and make sure that you have completed them.

While most of the pre-upgrade steps apply when upgrading from 11g, some of the steps, such as backing up your existing environment, will still apply - and are critical to the success of your upgrade. The list below describes the pre-upgrade steps you should complete before you upgrade your existing 12c Infrastructure:

• Section 2.1, "Backing Up Your Existing Oracle Fusion Middleware 11g Environment"

  Before any upgrade, be sure that you have created a complete backup of your current environment. If there is a problem with the upgrade, you may need to restore your environment and restart the upgrade process.

• Section 2.2, "Upgrading the Oracle Database"

  Review the latest system requirements and verify that your database is still supported.

• Section 2.8, "Installing Oracle Fusion Middleware Infrastructure 12.1.3 on APPHOST"

  You will need to install the 12.1.3 Infrastructure distribution before starting the upgrade.

• Section 2.9, "Installing Oracle HTTP Server 12.1.3 on APPHOST"

  If your 12c domain includes Oracle HTTP Server instances that are associated with the domain, you must upgrade to Oracle HTTP Server 12.1.3.

• Section 2.10, "Stopping Servers and Processes"

  The 12c upgrade is conducted completely offline. Make sure that all of the 12c servers and processes are stopped before starting the upgrade.
