Hi All, We're a shop running z/OS V1R6 and z/OS V1R7, looking into migration to z/OS V1R9
Migration manuals for z/OS V1R9 say nothing about supported migration paths for safely going from z/OS V1R6 to z/OS V1R9 and insuring safe fallback in case backing out is required (maybe IBM is only saying that such a scenario has not been tested) Looking into some APARs listed in the "Migration" manual (GA22-7499-11), I can occasionally spot PTFs per these APARs, for pre-V1R7 system components too(*), and I can glean them and install them on my z/OS V1R6 system Will it suffice ? Has anyone done such a migration leap and cares to share experience ? What do IBM staffers here have to say on this ? (*) For instance, the "Migration" manual (GA22-7499-11) lists UA22351 (APAR OA13525) as a PTF required for z/OS V1R7 IEBCOPY (HDZ11K0) to tolerate format-5 program objects introduced at V1R8. Looking up OA13525 at https://techsupport.services.ibm.com/server/zseries.srchBroker I can see it suggests UA22350 for HDZ11J0, UA22349 for HDZ11H0, and UA22348 for HDZ11G0. So, seems applying UA22350 is supposed to make V1R6 IEBCOPY (HDZ11J0) tolerate format-5 program objects. Isn't it ? Another example: The "Migration" manual lists UA24984 (APAR OA12922) as a PTF required for z/OS V1R7 JES2 (HJE7720) to coexist with V1R9 JES2 in a MAS. Looking up OA12922 at https://techsupport.services.ibm.com/server/zseries.srchBroker I can see it suggests UA24984 for HJE7720, UA24983 for HJE7708 (V1R5 JES2, this is the JES2 we have on our V1R6 system), and even UA24982 for HJE7707 (V1R4 JES2). So, seems applying UA24983 is supposed to make V1R5 JES2 coexist with V1R9 JES2, per this APAR. Am I wrong ? ____________________________________________________________________________________ Be a better sports nut! Let your teams follow you with Yahoo Mobile.
