Important Considerations for Upgrades

To upgrade successfully, read and follow these important considerations:

• If you are running CA Service Catalog Release 12.6 through 12.8, you can upgrade directly to Release 12.9 using either a traditional model or migration model upgrade.
• If you are running CA Service Catalog Release r12.5, the following options apply:
  • Upgrade directly to Release 12.9 using a migration model.
  • First upgrade to Release 12.6. Next, use a traditional model to upgrade to Release 12.9.
• If necessary, contact Technical Support to obtain the installation media for a previous release of CA Service Catalog, including the documentation. To perform this upgrade, follow the instructions from Technical Support, the Implementation Guide, and Release Notes.
• You cannot use the upgrade program to migrate from one DBMS to another. For example, you cannot upgrade a CA Service Catalog Release 12.7 installation running SQL Server to a CA Service Catalog Release 12.9 installation running Oracle.
• Beginning with CA Service Catalog Release 12.8, %USM_HOME% is no longer a Windows environment variable. Instead, USM_HOME is the documentation convention that specifies the local CA Service Catalog installation directory. For 32-bit computers, the default path name is C:\Program Files\CA\Service Catalog. For 64-bit computers, the default path name is C:\Program Files (x86)\CA\Service Catalog for 32-bit installations or C:\Program Files\CA\Service Catalog for 64-bit installations.
• The upgrade program upgrades CA Service Catalog in its existing installation directory, except in the following case: If you perform a migration model upgrade to CA Service Catalog Release 12.9 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.)
