My first install was OS/390 2.8 to upgrade an OS/390 1.2 system and I did exactly what you are proposing. To keep catalog issues from biting me, I'd do an export and import of the user catalogs to new clusters between tests.

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. This is something I have done many times on z/VSE, but not on z/OS and I know it's not as simple due to the ICF catalogs and such found on z/OS. Does anybody have a favorite document that describes such a move and the things we need to consider? Pointers to "free" tools would also be helpful as we decide which way to migrate this box. -- Tony Thigpen ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
