Chapter 1. Planning for Migration
This chapter provides information to help you plan your installation's migration to
the new release of OS/390 Security Server (RACF). Before attempting to migrate,
you should define a plan to ensure a smooth and orderly transition. A well
thought-out and documented migration plan can help minimize any interruption of
service. Your migration plan should address such topics as:
Identifying which required and optional products are needed
Evaluating new and changed functions
Evaluating how incompatibilities affect your installation
Defining necessary changes to:
– Installation-written code
– Operational procedures
– Application programs
– Other related products
Defining education requirements for operators and end users
Preparing your staff and end users for migration, if necessary
Acquiring and installing the latest service level of RACF for maintenance
The content and extent of a migration plan can vary significantly from installation to
installation. To successfully migrate to a new release of RACF, you should start by
installing and stabilizing the new RACF release without activating the new functions
provided. Installing the new RACF release without initially exploiting new functions
allows you to maintain a stable RACF environment. The program directory shipped
with the new OS/390 release gives detailed information about the correct software
required for installation.
When defining your installation's migration plan, you should consider the following:
Migration
Installation
Customization
Administration
Auditing
Operation
Application development
General users
Migration Planning Considerations
Installations planning to migrate to a new release of RACF must consider high-level
support requirements such as machine and programming restrictions, migration
paths, and program compatibility.
