How to Perform Prerequisite Tasks

Perform the following prerequisite tasks before you migrate CA Service Catalog. These tasks are required to help ensure that you can complete the migration process successfully.

1. Verify that the setup on the production system matches the setup on the test system. In other words, verify that the production system has CA Service Catalog installed on the same number of computers as the test system. Verify that the same products and components are installed on each computer in the production system as its "matching" computer in the test system.

   Thus, each test computer must have a matching production computer, and both of these computers must have the same CA Service Catalog components installed.

   For example, suppose the first test computer has installed Service View, CA Service Catalog, the Catalog Content (Best Practices Foundation), and CA Service Accounting. In that case, the first production computer must also have each of these components installed. Moreover, the production computer must not have any additional CA Service Catalog products and components installed.

2. Plan your migration. You migrate from the old system to the new system incrementally in pairs. Each increment consists of a migration process from one test computer to the "matching" production computer.
3. Verify that the business unit ID of the service provider is the same in both systems.

   Important! The service provider business unit ID for the new installation must match the previous installation.

4. Verify that all computers in both systems are at the same patch level for all important software. Examples include the DBMS, the MDB, any patches for CA Service Catalog products and components, including CA EEM, and so forth.
5. Verify that the CA EEM Application Name for CA Service Catalog is the same on both the test and production systems. By default, this name is Service Catalog.

   If necessary, update the Application Name, on either or both systems. For instructions, see your CA EEM documentation.

6. Back up an existing data that you want to keep for use after the migration, and copy the backed up data to a different computer. Any existing data is overwritten during the migration process.
7. Using the Windows Control Panel, stop the CA Service Catalog services on all CA Service Catalog computers: CA Service View, CA Service Accounting, CA Service Fulfillment, and Message Queue 4.1 Broker.
8. Back up the MDB of your production system, on the computer where the MDB is installed. This requirement applies, regardless of whether the system is installed on one computer or multiple computers.

   For instructions to back up the database, see your DBMS documentation.

9. Back up the MDB database of your test system, on the computer where the MDB is installed. This requirement applies, regardless of whether the system is installed on one computer or multiple computers.

You have performed the prerequisite tasks for migrating CA Service Catalog.
