Before you upgrade your existing Oracle WebCenter components, you must complete the mandatory pre-upgrade tasks.
Performing the Oracle Fusion Middleware Required Pre-Upgrade Tasks
Installing the Required Oracle Fusion Middleware Distributions for WebCenter
Before you being the Oracle WebCenter upgrade to 12c (12.2.1), complete all standard pre-upgrade tasks described in the Oracle Fusion Middleware 12c Pre-Upgrade Checklist.
Once you have completed the standard Oracle Fusion Middleware pre-upgrade tasks, review the WebCenter-specific tasks described in Performing the Oracle WebCenter-Specific Pre-Upgrade Tasks.
Some WebCenter products require additional pre-upgrade tasks. Review the component-specific sections of this guide to determine if any additional tasks are required for your environment.
This section includes pre-upgrade tasks that apply to any Oracle WebCenter products being upgraded to 12c (12.2.1). Perform only those tasks that apply to your environment.
Caution:
Failure to properly prepare for an upgrade may lead to unrecoverable errors and upgrade failures. Make sure that you have completed ALL applicable pre-upgrade tasks before beginning the upgrade.The pre-upgrade tasks for Oracle WebCenter include the following:
| Pre-Upgrade Task | More Information |

| Complete all general pre-upgrade tasks described in the Oracle Fusion Middleware 12c Upgrade Checklist (Required)
CAUTION: DO NOT continue with the upgrade until this task has been completed. |

| Complete the pre-upgrade tasks for Oracle WebCenter Content (if you will be upgrading Content.) | Performing Pre-Upgrade Tasks for WebCenter Content |
| Complete the pre-upgrade tasks for Oracle WebCenter Enterprise Capture (if you will be upgrading Enterprise Capture). | Performing Pre-Upgrade Tasks for Oracle WebCenter Enterprise Capture |
| Complete the pre-upgrade tasks for Oracle WebCenter Portal (if you will be upgrading WebCenter Portal) | Performing Pre-Upgrade Tasks for Oracle WebCenter Portal |
The following components should be disabled before the upgrade because they are obsolete or disabled as of Release12c (12.2.1).
Failure to disable these components may cause the upgrade to fail and content servers will not be able to start.

Before you can perform and upgrade to WebCenter 12c, you must install - but do not configure - the following Fusion Middleware distributions in your existing 11g domain:
| Distribution | Installation Guide |
|---|---|
| Oracle Fusion Middleware Infrastructure | Installing and Configuring the Oracle Fusion Middleware Infrastructure |
| Oracle WebCenter Content (if you are upgrading Content or Enterprise Capture) | Installing and Configuring Oracle WebCenter Content |
| Oracle WebCenter Portal (if you are upgrading Portal) | Installing and Configuring Oracle WebCenter Portal |
| Oracle SOA Suite and Business Process Management | WebCenter Content Imaging Upgrades Only: You must install Oracle SOA Suite 12c before upgrading Oracle WebCenter Content Imaging. If the 12c SOA binaries are not present, the upgrade will fail.
Installing and Configuring Oracle SOA Suite and Business Process Management |
You must create the following schemas in 12c before you can upgrade Oracle WebCenter:
Service Table (_STB)
Oracle Fusion Middleware 12c introduces a new required schema called Service Table (_STB). This schema is automatically created when you run the Repository Creation Utility (RCU) and must be created before you can upgrade your existing 11g deployment. For more information, see Understanding the Service Table Schema.
Oracle Platform Security Services (_OPSS)
WebCenter does not use the _OPSS schema directly, but requires that the OPSS schema be upgraded as part of the upgrade process. If you do not have an Oracle Platform Security Services (_OPSS) schema in your 11g environment, you must create one for 12c.
Audit Schemas (OPSS_AUDIT_VIEWER)
If you used an XML-based OPSS_AUDIT schema in 11g, then you will need to create a new 12c OPSS_AUDIT_VIEWER schema or the domain reconfiguration will fail.
To create the new schemas, you will use the Oracle Repository Creation Utility (RCU).
Note:
When creating the new schemas, use the existing prefix, that is, the prefix used for 11g schemas.To access the RCU:
On UNIX operating systems:
cd ORACLE_HOME/oracle_common/bin
./rcu
On Windows operating systems:
cd ORACLE_HOME\oracle_common\bin
rcu.bat
For more information on using the RCU, see Creating Schemas
This table describes the WebCenter schemas that can be upgraded to 12c.Your environment may or may not use all of these schemas.
Table 2-1 WebCenter Schemas that can be upgraded
| Component Name | Schema(s) | Schema Version Before Upgrade | Schema Version After Upgrade | Dependencies |
|---|---|---|---|---|

Oracle Enterprise Capture |
|
11.1.1.8.0 11.1.1.9.0 |
12.2.1 |
Metadata Services (_MDS_ Capture is an ADF application and therefore requires the MDS schema be upgraded before the WebCenter servers are started. Oracle Platform Security Services (_OPSS) Capture does not use the OPSS schema directly, but requires that the OPSS schema be upgraded as part of the upgrade process. |
