Implement System Managed Storage (DFSMS)
It is strongly recommended that DFSMS be planned for and implemented from
day one of the migration. The key benefit of implementing DFSMS is how it helps
the installation be positioned for future growth. Implementing DFSMS also helps
the conversion by providing structure for standards and naming conventions.
Other benefits of installing DFSMS from the outset are:
 1. No future conversion of the configuration is required.
 2. Positioning for new software function and hardware support where most new
functions in OS/390 have SMS as a prerequisite. Examples include data
compression and extended data sets.
 3. Provides DASD management.
 4. Supports cataloging all your data sets from the beginning.
 5. Less complicated JCL from a VSE user perspective through the use of data
classes.
32.4.1 Phase 0: Project Management and Technical Leadership
A Project Manager/Technical Leader is assigned the responsibility for
administration and technical direction of the conversion efforts. Project
management activities consist of:
Developing detailed work plans and schedules
Evaluating the progress made against work plans and schedules
Conducting weekly progress review meetings
Conducting monthly project status reports
Providing liaison and coordination between all personnel involved
32.4.1.1 Project Planning and Orientation
The objective of this task is to develop detailed project plans and orient the
conversion team and all personnel involved to the conversion approach and to
the project plans. The project plans include:
Overall project plan
Online application test plan
Batch application test plan
Switchover plan
It is recommended to use a project management software tool to develop and
update the project plans. An example of a project plan is provided in Chapter 3,
“Developing the Plan” on page 41.
