Generations of Supercomputing

Migration from MVS to VSE-ESA

Finding the right support team !

Including the development teamat every step of the migrationprocess

Going past the point of no return

Where angels fear to tread!

Generations of Supercomputing

Migration from VSE-ESA to zVSE

Finding the right CPU !

Generations of Supercomputing

The need to create disaster recovery facilities

The many scenarios

The new IBM z114 and z196

The need to migrate to an open platform retaining the ability to read historical (zVSE) data
