Always use the stand-alone dump version that is generated from the same release of z/OS® that you want to dump. IBM® does not guarantee that a different level of stand-alone dump will successfully dump anything other than the level of z/OS it was designed for. The new version of z/OS might have changed making the stand-alone dump program unable to locate vital information it needs to operate.
When migrating to a new version of z/OS, IBM strongly recommends that you generate a new version of the stand-alone dump program built from the new z/OS system data sets. See One-stage generation for more information.
