RC/Migrator for DB2 for z/OS
Issue/Introduction
Is there an easy way to propagate RC/Migrator for Db2 for z/OS (RCM) migrations to multiple targets.
Resolution
A Group Analysis of a Migration Strategy utilizes Copy Group services to facilitate migrations to multiple targets within a single analysis.
Here are the necessary steps:
Execute the 'Group Analysis'
From the RC/Migrator (RCM) Strategy Services enter a 'G' line command to the left of the migration strategy in order to execute the Group Migration Strategy Analysis.

Select a Copy Group and other analysis options:
Group Migrations require the use of Copy Groups. A Copy Group consists of 1 or more Copy IDs that specify target information including Target SSID, Global Changes and Utility Specifications. In Group Migrations, the target SSID is defined for each Copy ID in a Copy Group set; the Target SSID field on the RC/M Group Migration Strategy Analysis screen is ignored but must be specified. In a Group Migration, global changes can be specified for each Copy ID in a Copy Group set; all specifications apply. Global changes specified on the Analysis screen (not in the copy group set member), are appended to each copy group set member's global change set in the copy group set. The first global change specification that can be applied to an object is used.
From the Group Migration Strategy Analysis screen, Copy Group settings can be defined by entering an 'S' (Select) in the Copy Group field under COPY GROUP SPECIFICATIONS, allowing access to the RC/M Copy Group Services screen where Copy Groups can be selected, created, updated, tem plated, deleted or browsed.

The first analysis above uses Managed Output(first three lines) and a second analysis using output to a PDS dataset (second three lines).
Each one of the analysis outputs above targets the subsystems identified in the COPY GROUP defined and all generated in one analysis job and individual output for each Copy Group member.
Execute the DDL
From the RC/Migrator Strategy Services screen, execute the DDL (now listed under the Migration Strategy) by entering an 'S' (submit) to the left of the DDL analysis row above.
