A financial institution cannot afford
downtime when moving from legacy
storage to newer storage arrays.
5. Old volumes were removed from configuration.
6. TDMF software was left on the system and used to move two volumes non-
disruptively within the new storage array to resolve performance problems
caused by pathing issues in the new hardware.

Local mainframe array-to-array migration
In this scenario, a large Canadian bank running a credit and debit transaction
application on the IBM z/OS platform was moving from legacy storage to
newer storage arrays.
The challenges the bank faced included the following:
• No application downtime allowed—The application was a key revenue driver,
requiring 24x7 access. The projected 18 hours of downtime to install and con-
figure new arrays and complete migration would violate corporate IT policy
and cost thousands of dollars in lost revenue.
