Scope and Limitations of an Upgrade

Important! Read and understand the scope and limitations of the upgrade before performing the upgrade!

The scope and limitations of the upgrade are as follows:

• If you are running CA Service Catalog r12.5, you can upgrade to CA Service Catalog 12.6 using either a traditional model or a migration model.
• If you are running CA Service Catalog r11.2 Service Pack 2 or Service Pack 3 (r11.2) or CA Service Catalog r12, do one of the following:
  • Upgrade directly to CA Service Catalog 12.6 using a migration model
  • Upgrade to CA Service Catalog 12.6 using a traditional model; you must first upgrade to CA Service Catalog r12.5 as a prerequisite

    Important! If this option applies, contact Technical Support to obtain the CA Service Catalog r12.5 installation media, including its documentation. Follow the instructions in the Implementation Guide and Release Notes carefully to perform this upgrade.

• When you upgrade CA Service Catalog, you must upgrade all existing installations of the CA Service Catalog products and components. If you upgrade any CA Service Catalog component on any computer, you must also upgrade all other existing CA Service Catalog components on that computer and on any other computers in your environment.
• Verify that CA Service Catalog supports your database management system; if necessary, update your database management system to a supported version.

  You cannot upgrade from one DBMS to another. For example, you cannot upgrade a CA Service Catalog r12.5 installation running SQL Server to a CA Service Catalog 12.6 installation running Oracle.

• This point applies to traditional model upgrades only. When you upgrade a computer that already has CA Service Catalog components from a previous release installed, you cannot install any new CA Service Catalog component (one that has not been installed previously) on that computer. However, you can install the new component on a different computer.

  For example, suppose Computer A has Service View r12.5, CA Service Catalog r12.5, and Catalog Content r12.5 installed. When you upgrade Computer A, you upgrade only those components to Release 12.6; you cannot install a new component, such as CA Service Accounting 12.6, on Computer A. Instead, install CA Service Accounting 12.6 on a computer that has no existing CA Service Catalog r12.5 components already installed.

• You cannot change locale operating systems when you upgrade. For example, you cannot upgrade a CA Service Catalog r12.5 installation on an English operating system to a CA Service Catalog 12.6 installation on a Japanese system.
• Service View upgrades have been observed to take a significant amount of time on Windows 2008 computers.

Note: If you upgraded from CA Service Catalog r11.2 to CA Service Catalog r12.5 immediately before you upgrade to CA Service Catalog 12.6, be sure to read and follow all information and instructions regarding features removed in CA Service Catalog r12, especially Unicenter Service Meter. For details, see the CA Service Catalog r12 documentation, especially the Implementation Guide and Release Notes. As a precaution, the MDB retains data related to Unicenter Service Meter in case it can be used by other CA products that include Unicenter Service Meter.
