Upgrading to version 14.1.2.0.0 is only supported when the starting version is 12.2.1.4 or 12.2.1.19.

Before you continue, it is recommended that you first create a backup of the existing Oracle Home and Domain.

When planning an upgrade, you will need to decide where to install the software. There are two options:

• Use the same Oracle Home path where the previous version is installed. This is referred to as an "in-place" upgrade.
• Use a new Oracle Home path. This is referred to as an "out-of-place" upgrade.

In-place upgrades assume you would like to continue to use the same Oracle Home directory path as used previously. In this case, you would rename the existing Oracle Home directory, install the new software in the directory path that was previously used, then copy over any required files from the backup (renamed) directory. Then run WLS Reconfiguration Wizard and Upgrade Assistant as instructed in this chapter.

Out-of-place upgrades are used when you want to install Oracle Forms in a new directory path. For this option, install the software as for a fresh installation into a new directory path. Then run WLS Reconfiguration Wizard and Upgrade Assistant as instructed in this chapter.

The exact steps you will need to complete may depend on the type of upgrade you are doing as well as your starting version. Review the sections in this chapter carefully to determine which procedures are required for your environment.

If your current version is earlier than 12.2.1.4, you need to first upgrade to 12.2.1.4 or 12.2.1.19 before proceeding. Refer to the appropriate version Installing Oracle Forms for information on how to upgrade to that version.

When you believe you have a working 12.2.1.4 or 12.2.1.19 environment, return to this document and continue.
