Step 4: Migrate Data to the CA IDMS/DB Database

Convert Data Structures Using the Migration Utility

You can use the CA IDMS VSAM Transparency migration utility (ESVSMIGR) to migrate VSAM data to an CA IDMS/DB database. This utility works with CA IDMS VSAM Transparency to convert KSDS, ESDS, RRDS, and alternate index data structures to CA IDMS/DB data.

Steps to Follow

To use the CA IDMS VSAM Transparency migration utility:

  1. Use the FORMAT utility statement to initialize the area where the converted data will reside. (The FORMAT utility statement is described in CA IDMS Utilities Guide) If the area has already been initialized, you do not have to follow this step.

    Note: You can load VSAM data into any standard CA IDMS/DB area, including an existing area that already contains data.

  2. Run the migration utility, using the FMT defined for the file to be migrated. If you have not already defined an appropriate FMT, refer to Preparing Control Information, for instructions.
