IIRC Coexistence/migration support was N-3 in the OS/390 days (with a new dot release every 6 months). My memory if very foggy about the exact time frames, bit I believe N-2 has been in effect since about os/390 1.6 Certainly for many years.
HTH, -----Original Message----- From: IBM Mainframe Discussion List <[email protected]> On Behalf Of Clark Morris Sent: Wednesday, November 7, 2018 8:18 PM To: [email protected] Subject: Supported release for z/OS When did IBM change its support policy so that after an overlap period only the 2 most current release are supported. I was surprised to find that End of Service for 2.1 was September 2018 since 2.3 is the current release.
