Migrating a z/OS® Communications
Server system from a previous release involves considerable planning.
To familiarize yourself with the migration process, review this checklist.
Tailor the checklist to meet the specific requirements of your installation.
Procedure
- Understand your network topology, including the hardware
and software in your network and your network configuration.
- Understand that z/OS V2R1
Communications Server is
a base element of z/OS. Use the appropriate documents as you plan, migrate, and install:
- Develop your education plan.
- Evaluate the z/OS V2R1
Communications Server features
and enhancements by reading the new function summary topics in this
document.
- Plan which new functions will be incorporated into your
system.
- Review and apply the Program Temporary Fixes (PTFs), including
Recommended Service Upgrades (RSUs), for the current-minus-3 month
plus all hipers and PEs. The PTFs are available monthly through the
period for which the release is current and can be obtained by using
IBMLINK. RSU integration testing for a release will be performed for
five quarters after the general availability date for that release.
- Get acquainted with the helpful information found at z/OS Communications
Server Support.
- In writing a test plan for z/OS, include
test cases for these items:
- TCP/IP applications
- Key or critical SNA applications and Original Equipment Manufacturer
(OEM) software products.
- User-written applications such as: Customer Information Control
System (CICS®) sockets, Information
Management System (IMS™) sockets,
REXX sockets, Sockets Extended, UNIX System
Services sockets, and Macro Sockets
- Operator commands
- Your terminal and printer types
- Back up your user exits and user modifications for later
restore.
- Install z/OS Communications
Server with the other elements and features of z/OS. IBM® has defined the appropriate
product enablement settings in the IFAPRD00 member of SYS1.IBM.PARMLIB.
For information about dynamic enablement, see z/OS Planning for Installation.
- Complete post-installation activities:
- Use z/OS Communications Server: IP Configuration
Guide to customize your TCP/IP system.
- Use the following information to customize your SNA system:
- Use z/OS Migration to
determine migration actions.
- Reinstall user exits.
- Reinstall user modifications.
- Update operating procedures and automation routines.
- Activate new functions.
- Complete functional and stress tests.
