The ADSO Migration Utility has been designed to facilitate the movement of entity structures and definitions between CA-IDMS Integrated Data Dictionaries. While it was originally developed, in 1983, to support ADS/ONLINE, its current functionality provides benefits to all CA-IDMS users.
The AMU mimics, while automating, the exact procedure which you would perform manually. It determines which component entities must be migrated, performs a complete impact analysis, and creates CA-IDMS compiler syntax to accomplish the actual migration.
Unlike other migration tools, the AMU only migrates those entities which are in need of migration, i.e. those entities which do not exist in the receiving dictionary, and those entities which do exist but are different. To make this determination, the AMU performs a complete structural comparison of each entity. Or, if you prefer, it can simply compare the most recent update date.
A large migration can be reduced to several hours of total execution time, with considerably less human intervention required. And you have the assurance that there will be no omissions or typographical errors. During a modification or enhancement cycle, the AMU will validate that proper change control procedures have been followed, and will inform you of any affected entities which have not been addressed.
The AMU, additionally, provides a number of facilities which are not available through the CA-IDMS compilers such as changing versions of dialogs or programs, migrating USER passwords, and automatically varying new copies of programs. Several reporting features are also included.
The AMU is supported in all environments which support any manifestation of COBOL.
Release 12 of the AMU may be used with dictionaries supported by any release of CA-IDMS
While it is recommended that you read this manual from cover to cover, we realize that it is highly unlikely that this recommendation will be followed. So, this is an attempt to highlight the required reading for new users of the AMU.
The Installation section explains the installation of the AMU.
System Flow within the System Description section will provide you with a high level overview of the entire system.
The Overview of each Phase (I through V) will provide you with a somewhat more detailed explanation of each step.
Read Migration Status and Replacing Modified Entities within Phase II for background information before proceeding to Phase III.
Input Statement Types in Phase I and Phase III describe the types of input specifications which are available.
At least one Selection Criteria statement is required in Phase I, and User Signon statements are required in Phase III. If you are migrating from or to a secondary dictionary, then Dictionary Definition statements may also be required in Phase I. All other input is optional.
After completing the required reading, you may wish to execute Phases I through III to get the feel of the AMU. All listings should be examined and fully understood. The reports generated in Phase II (LADAMU10-1, LADAMU10-2, LADAMU12-1, LADAMU12-2) are the most important of these, as they display exactly what will or will not be migrated and the reasons for that determination.
Now that you understand the basics of the AMU, you will certainly want to read the manual from cover to cover. If not, at least look through the table of contents and choose those sections that appeal to you.
