Would there be any concerns with internal changes to system dataset structures? As an example like catalogs or things like HSM CDS datasets? Going from z/OS 2.1 to z/OS 2.4 is technically not support for fallback. Would it be a good thing to at least try to get any z/OS 2.3 compatibility maintenance applied? That might get you nearer to a level that could help if you had to fallback.
From the z/OS Planning for Installation manual for z/OS 2.4 z/OS V2R4 is supported for coexistence, fallback, and upgrade with the following z/OS® releases: z/OS V2R4, V2R3, and V2R2. This means that: •Coexistence of a z/OS V2R4 system with a V2R3 and V2R2 system is supported. •Fallback from a z/OS V2R4 system to a V2R3 or V2R2 system is supported. •Upgrade to a z/OS V2R4 system from a V2R3 or V2R2 system is supported.
