Gadi, You can learn about the z/OSMF Software Management installation process here: https://www.ibm.com/support/z-content-solutions/serverpac-install-zosmf/
I would strongly recommend that you watch the short videos (under Multimedia at the bottom) to get a flavor of what it looks like in action. Then do a practice install with a sample package which you can acquire from the "Try it" tab on that website. z/OS V2.3 (with z/OSMF active) is a fine driving system level for installing z/OS V2.5, but as you mention, is longer supported. Just make sure you follow the driving system requirements documented in the z/OS V2.5 Planning for Installation book. You could also acquire the Customized Offerings Driver (free driving system, orderable on Shopz), if you wanted to use a supported driving system level that has z/OSMF already active on it. -Marna WALLE z/OS Install and Upgrade IBM Poughkkeepsie ---------------------------------------------------------------------- For IBM-MAIN subscribe / signoff / archive access instructions, send email to lists...@listserv.ua.edu with the message: INFO IBM-MAIN
