General CA Process Automation Upgrade Considerations

The Installation Guide that accompanies CA Process Automation 4.2 contains the information you need for successful upgrade. For example:

• Planning and pre-requisite checking is of paramount importance when upgrading to CA Process Automation 4.2. We strongly recommend that you read the "Upgrade to the Current Release" section in the Installation Guide before proceeding.
• Beginning with CA Process Automation v4.0, you must configure the product to use CA Embedded Entitlement Manager (CA EEM). If you previously used a directory service such as Microsoft Active Directory or another LDAP-compatible directory service with CA Process Automation, you can configure CA EEM to use it as the external user store.
• CA Process Automation 4.2 installation or upgrade requires that you have Java Development Kit (JDK) 1.7 on the target host. See "Platform Support and Requirements for CA Process Automation Components" in the accompanying Installation Guide for details such as this.
• The earliest release supported for upgrade is 3.1 SP01. If you are upgrading from an earlier release than 3.1 SP01, download CA Process Automation 3.1 SP01 from support and upgrade your release to r3.1 SP01. Then, upgrade from 3.1 SP01 to 4.2 as described in the CA Process Automation Release 04.2.00 Installation Guide.

  Note: The initial upgrade can take several hours to complete due to extensive schema changes.

• CA Process Automation 3.1 SP01 functions perfectly even when installed on machines with non-standard DNS host names, for example, a host name that includes the underscore character. This is not the case with CA Process Automation 4.2. Therefore, DNS host names must strictly adhere to naming standards. For more information, see the Installation Guide.
