IBM DATA MIGRATION SERVICES - Brochure - page 19
Softek’s TDMF UNIX (IP) software was chosen based on its ability to migrate
between disparate platforms and its flexibility in working with various logical
definitions. The benefit of the TDMF solution is that the data migration could
be performed in a challenging environment well within scheduled windows.
The firm was finally able to take advantage of its new hardware, which enabled
it to run queries four times more quickly with the new array, improve data
layout, and greatly simplify administration. Most important, end user complaints
about performance were eliminated almost entirely. In addition, the firm was
no longer paying lease charges for unused or outdated hardware. Softek’s
implementation methodology ensured that there were no manual errors and the
onsite resources were used efficiently.
