A combination of Softek’s TDMF and LDMF software was chosen because of the
products’ ability to migrate data nondisruptively, handle the resizing of MODs,
and move specific data at the dataset level. With the LDMF/TDMF combination,
the project was completed ahead of schedule (60 hours estimated, 55 hours
actual), with data migration constituting 38 hours of the total time. This was
considerably shorter than anticipated, and the migration was performed while
the mainframe was in production, with no impact to end users.
Softek solution: Local mainframe migration with volume consolidation
1. TDMF and LDMF software was nondisruptively installed on IBM Z800
mainframe and verified by the implementation team.
2. The team mapped source and target volume migration for TDMF migration.
As part of the process, TDMF software was used to migrate a single source
MOD 3 to a MOD 9, thereby establishing the target MOD 9 into the existing
storage management subsystem (SMS) environment and eliminating any
SMS setup requirements for the new MOD 9 volumes.
3. The team mapped the remaining MOD 3 to MOD 9 migration, which was
accomplished using LDMF software. The mapping documented the target-
volume SMS storage groups and storage class. This also identified any
volumes that were not under SMS control.
4. TDMF migration was initiated. Over the course of ten hours (including
verification), the implementation team migrated 200 MOD 3 to 200 MOD 3
and 240 MOD 3 to 240 MOD 9. This entire migration was completed trans-
parently during production hours.
5. The implementation team set up LDMF migration by building source and
target dataset migration groups (460 source volumes going to 240 target
volumes at the dataset level).
Storage migrations made simple.

After evaluating several migra-
tion methods, a savings and loan
company chose Softek’s TDMF and
LDMF software due to their ability
to migrate data nondisruptively,
resize MODs and move specific
data at the dataset level.
