Implementing Migration Procedures

Steps

There are essentially four steps involved in migration:

1. Determine the types of components to migrate

   Carefully examine the circumstances for dependencies and other relationships among the components involved.

2. Determine the sequence of migration

   Components that do not depend on the definitions of other components should be first on the list.

3. Identify the components

   Identify the names, version numbers, and, as appropriate, languages of the individual components that you need to migrate.

4. Migrate the components using the batch and online compilers and utilities

These steps are discussed on the following pages.

Before You Begin

Before you begin a migration, you may want to back up all involved files. These files can include:

• Source and target DDLDML, DDLDCLOD, DDLCAT, DDLCATX, and DDLCATLOD areas
• Source and target source libraries
• Source and target load libraries
• Source and target JCL procedure libraries

These backups provide coverage during the migration as well as after the migration is complete. If problems arise at any time, you can restore individual components or entire files from the backups.
