40 IBM CSM to IBM Systems Director Transformation Guide
3.1 Overview of the scenarios
The two scenarios have two different approaches for transformation. The first scenario is
more conservative and relies on reusing the old infrastructure. The second scenario uses a
new physical infrastructure for both the IBM Systems Director Server and NIM Server and
focuses on keeping existing capabilities in place as well as implementing new functionalities
only available in IBM Systems Director.
Here is a brief description of the two scenarios:
? Coexistence Scenario - CSM Management Server and the IBM Systems Director Server
in the same operating system on the same server.
? Migration Scenario - CSM Management Server and IBM Systems Director Server on
different servers.
In order to provide familiarity with both management interfaces of IBM Systems Director we
have focused on the Graphical User Interface for the first scenario and the command line
interface for the second scenario. No matter what path you choose when transforming your
CSM cluster, we recommend that you read both scenarios and familiarize yourself with both
interfaces because some tasks may only be available through one interface.
The transformation scenarios show the movement of one or more nodes at a time from CSM
to IBM Systems Director while CSM is up and running.
3.1.1 What we do not cover
The following topics are not covered in this publication:
– Installation and Administration of CSM
For detailed installation and administration steps, refer to the CSM Installation Guide
at:
http://publib.boulder.ibm.com/epubs/pdf/a2313435.pdf
– Installation and configuration of IBM Systems Director
For detailed installation and configuration of IBM Systems Director for AIX, refer to:
http://publib.boulder.ibm.com/infocenter/director/v6r2x/topic/com.ibm.direct
or.main.helps.doc/fqp0_bk_install_gde_aix.pdf
– NIM installation and configuration
For information related to NIM, refer to:

doc/insgdrf/nim_intro.htm
Notes:
? We strongly recommend having both CSM and IBM Systems Director active at the
same time because this should be a temporary solution. Once the transformation is
complete, CSM should be decommissioned.
? Before transforming your environment we strongly recommend to have full backups of
all machines and CSM. For information about CSM backup refer to 5.4, “Backup and
restore of the management server” on page 139.
