Inventory Mainframe Technical Assets

**Description**

As we are planning to migrate entities from the Mainframe to the modernized system, we should conduct a technical inventory of the Mainframe/COLIN application to identify the technical assets that support each in-scope business entity. This inventory will provide the technical foundation for data mapping, migration design, and implementation planning

The objective is to document where entities are stored, how they are processed, and the technical components involved in their lifecycle.

Review the linked BCRS Mainframe Applications Overview, Mainframe Migration System Context Diagram, Mainframe Migration Runbook, colin_lear_data_mapping.xlsx, and README_COLIN_Corps_Extract. Confirm that the inventory covers storage, processing, dependencies, interfaces, environments, gaps, and migration risks; done means every listed checklist area is documented.
