Couple of thoughts 1) Find and download all the MIGRATION GUIDES from IBM
2) Find and download all of the Marna Walle Presentations on Migration from share.org 3) Two ways to do this. One is to just install the new z/OS and then port the applications and test. There are some major changes in control blocks from your release and up. So you may want to validate what will work. Migration guides will help. UCB moved to above the line TCB moved to above the line Language Environment changes need to be reviewed (THDTERMACT and Storage) Which version of the z/OS? If z/OS V2 + COBOL Compiler V5+ then you need to ensure application libraries are PDS/e Some other I am sure But Export/Import the cats will be a good process Lizette > -----Original Message----- > From: IBM Mainframe Discussion List [mailto:[email protected]] On > Behalf Of Tony Thigpen > Sent: Tuesday, January 02, 2018 11:34 AM > To: [email protected] > Subject: migration to new z/OS release > > I am just now starting the research on migrating an os/390 machine to z/OS. > Currently, it is running on a z/10, and we will use an z/OS that is > compatible with the z/10, so a hardware conversion is not an issue. > > This OS/390 system has been managed by multiple out-sourcers and bastardized > to the point that we would like to consider just installing a new, clean > z/OS, then migrating the data to it.
