MAPPER Downsizing/Migration (From UNISYS 2200 to MAPPER/C environment) Arran Technologies has a proven data migration/code conversion methodology to manage MAPPER Migration projects of any size. The major milestones of a MAPPER migration project are detailed in the following figure. MAPPER Migration Milestones 1. Inventory & Assessment – An Inventory & Assessment is performed against the applicable MAPPER systems/applications. The result is a working task list of Runs, subroutines and all database elements to be used throughout the migration process. 2. Cross Reference Tables – Complete details of which Runs access what databases and other subroutines and/or Runs and vice versa. 3. Data Conversion – Implementation of MAPPER applications and databases created via subroutines and scripts developed per database specifications. 4. MAPPER Program Code Conversion – MAPPER program code analysis verifying compatibility of execution in a MAPPER/C environment. 5. Unit Test – Each MAPPER program is unit tested with converted code and converted databases. 6. System Test – A base line unit test is established from the 2200 MAPPER environment. The result of the baseline test is compared to the unit test results from the new MAPPER/C environment. 7. Mock Conversions – Conversion scripts created through the Data Conversion process are executed. Data Validation and System Testing efforts are reiterative until successful business results are achieved.
