EMMz

Essential Mainframe Migration for z/OS (EMMz) is z/OS mainframe based software that enables local or remote global data migration for storage attached to IBM z/OS mainframes across multivendor environments. It provides data migration for both z/OS and z/VM volumes. EMMz is vendor-independent as well as user- controlled. It allows for full system sharing throughout the data center and guarantees full access to the data at any point during a migration operation. It also supports dynamic takeover on the part of the target device while applications remain online. Taking advantage of investments in new storage technologies can be done more quickly, with minimal disruption.
