IBM Transparent Data Migration Facility (TDMF) z/OS and IBM z/OS Dataset Mobility Facility (zDMF)

Effective data migration with continuous application availability

Migrating data across heterogeneous storage environments can be risky, disruptive, time consuming and expensive. You need the right software to achieve a non-disruptive migration that helps ensure continuous application availability. IBM® Transparent Data Migration Facility (TDMF®) z/OS® and IBM z/OS Data Set Mobility Facility provide vendor independent data migration while applications remain online, thus helping to ensure a more rapid and seamless data migration.


IBM TDMF z/OS and zDMF migration software have been designed to provide host based, end-to-end data migration that is non-disruptive. TDMF z/OS data migration is at the volume level, while zDMF migrates data at the dataset level. These software products can help you avoid the risk of data loss and reduce your overall storage costs - regardless of vendor and disk capacity.

IBM is one of the leading providers of data migration solutions and has helped many organisations migrate data for their IBM z/OS mainframes. We have executed over 2,500 data migrations using IBM TDMF z/OS in more than 800 companies across the globe. Our solutions leverage the expertise of experienced storage specialists to help you migrate data more effectively, with reduced complexity, on time and within budget.
