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!
1994
Generations of Supercomputing
Migration from VSE-ESA to zVSE
Finding the right CPU !
2008
Hitachi PilotIBM z800
Fast forward 2004
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
Generations of Supercomputing
IBM zSeries (z114)

Generations of Supercomputing
Going past the point of no return
An auditor's nightmare!
Migration from zVSE tozlinux – SUSE Enterprise
Having the right support team !
Including the development team at every step of the migration process

Generations of Supercomputing
Faster production backups (Ex VTape)Reducing printing costs (PDF)Simpler line printing solutionsSimpler network printingSimpler work file handling (Programmers)Easier to implement front ends (PHP)
