z/OS Data Migration: Helping Clients
Avoid Risk and Downtime
By Rob Trovinger

O

rganizations undertake data
migrations for many reasons: a technology refresh,
infrastructure optimization, consolidation of servers and storage, or
data center relocation. Those faced
with a migration often have a host
of concerns about the potential
risks, including the possibility of
downtime for their business.
IBM data migration software
is available to address common
challenges and ease the pain
points that clients face with data
migration. For IBM Z* clients, IBM
offers Transparent Data Migration
Facility (TDMF) for z/OS* and
z/OS Data Set Mobility Facility
(zDMF) to migrate data while
maintaining continuous or nearly
continuous system and application
availability. 

TDMF and zDMF deliver
an essential service for IBM Z
environments. But having access
to helpful tools isn't the same as
knowing how to use them.

What are TDMF and zDMF?
TDMF and zDMF enable nondisruptive or nearly nondisruptive data
migration so that applications can
remain online during data migration execution. TDMF operates at
the volume level, while zDMF operates at the data set level.
Common use case scenarios
include:
*

Technology refresh/lease
expirations: Users who must
migrate existing data from old
storage arrays to new storage
arrays before the old storage

migration specialist with IBM Systems Lab Services.

arrays can be removed and/or
before maintenance contracts
expire
Infrastructure change
(optimization): Users who have
a need to redesign or adjust
their storage architecture
to improve efficiency and
performance, to accommodate
new or updated applications,
or to align data criticality with
storage cost
Consolidations: Users who
need to consolidate storage
arrays to reduce the storage
footprint in their data center.
Or environments experiencing
UCB constraints that have
a need to consolidate many
smaller volumes into fewer
larger volumes.
Relocation: Users who need to
migrate z/OS data from one or
several existing data centers
into one data center location.
TDMF is often the solution
of choice when a data center
relocation is required for a
remote distance migration
using TCP/IP. This is especially
true in a multivendor storage
environment.

What Is the Value of
This Software?
In addition to helping IBM Z clients
undergo data migrations with little
or no downtime, TDMF and zDMF
support the business imperatives
of minimizing risk, protecting data
integrity and ensuring regulatory
compliance. 
Do-it-yourself alternatives
typically require manual effort
and run the risk of data integrity
exposures, lengthy project durations
and costly business disruption. 
Moreover, TDMF and zDMF
can migrate data no matter which
vendor's storage it's currently
allocated to. This is possible
because TDMF and zDMF are both
host-based migration tools, which
means that as long as the z/OS
