Decide whether to perform a traditional or migration model upgrade. Note the value of all parameters for all business units in your implementation before you upgrade. After you upgrade, set the parameters accordingly.
  • If you are running CA Service Catalog 12.6 through 12.9, you can upgrade directly to the current release using
    either
    a traditional model or migration model upgrade.
  • If you are running CA Service Catalog 12.5, the following options apply:
    • Upgrade directly to the current release using a migration model.
    • First
      upgrade to 12.6. Next, use a traditional model to upgrade to the current release.
  • You
    cannot
    upgrade from one DBMS to another. For example, you cannot upgrade a CA Service Catalog 12.7 installation running SQL Server to the current release of CA Service Catalog installation running Oracle.
  • The installer upgrades CA Service Catalog in its existing installation directory, except in the following case: If you perform a migration model upgrade to the current release of CA Service Catalog on a 64-bit computer, CA Service Catalog is upgraded to a 64-bit application, and its default installation directory is updated accordingly. (CA Service Catalog Release 12.6 and 12.7 were supplied as 32-bit applications.)
If required, also review the Hardware Requirements and Installation Prerequisites before you proceed with upgrading CA Service Catalog.
Traditional and Migration Model Upgrades
You can upgrade CA Service Catalog to the current release using
either
a migration model or a traditional model.
  • In a traditional model, you upgrade on existing CA Service Catalog computers.
  • In a migration model, you install the current release of CA Service Catalog on
    new
    computers. When you install CA Service Catalog on the new computers, you use the Catalog database and CA EEM computers.
The migration model works as follows:
Consider this sample scenario: Your setup has Catalog Component and the Catalog database on existing Computer 1. Catalog Component and Service Accounting Component are on existing Computer 2, and CA Process Automation on existing Computer 3. Perform the following actions:
  • Verify that the current release of CA Service Catalog Release supports the DBMS version on existing Computer 1.
  • Verify that the DBMS client software is installed on the new computers on which you plan to run the upgrade.
  • Install Catalog Component on new Computer 4, pointing to the existing Catalog database on existing Computer 1. Similarly, install Catalog Component and Service Accounting Component on new Computer 5. When you are prompted for information about the Catalog database or CA EEM, use the
    existing
    Catalog database and CA EEM specifications, such as the CA EEM host name and application name.
  • Utilize CA Process Automation on Computer 3.
    Do
    not
    upgrade or delete CA Service Catalog on existing Computer 1 until all other computers are upgraded to the current release of CA Service Catalog and are running successfully.
