Sridhar, Theoretically, you could just apply the templates for the target z/OS release to the old database and reIPL with it. This assumes the database in the restructured format introduced with RACF 1.9 (MVS/ESA). However, there are many other factors that would determine whether your system would run effectively such as (just to name a few) whether there are exits involved (both RACF and other products calling RACF), what resource classes and profiles are defined, what release of CICS are you migrating from/to (there was a significant change in CICS transaction security at release 4.1), and what release of z/OS you are migrating to (for instance, FACILITY class profiles to allow the use of HSM commands are required in z/OS 1.6 and later). Depending on the size of the RACF database and the span of releases, you may need 2 to 4 weeks or more just to analyze the possible impacts and plan the creation of new profiles needed to accommodate the requirements of the target z/OS release.

G'day, I want to know from a technical perspective if some one needs to migrate an existing system from an older version of OS (say MVS/ESA, OS/390 etc to Z/Os) what is the impact on RACF?. Would migrating the RACF to a newer version be a big enough Project(like a 6 months to 1 year kind of project)?. Or as in any migration from one version to another, RACF is also automatically handled?. Please advice. Thanks in advance for your response.
