IBM DATA MIGRATION SERVICES - Brochure - page 16
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.

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.
