This section describes the authorization requirements for administration and operation of AWS Mainframe Modernization and the access requirements for system and user datasets allocated during the z/OS installation process.
Note: While the z/OS distribution datasets referred to in this section contain the node V4nnnn corresponding to Version 4, Release/Build (rrbb), it is recommended incrementing only the Release number when a new build is installed to minimize the impact on JCL, e.g: V400, V401, V410.
