We recommend that you set up a change management plan to make the project a success, with emphasis on the internal promotion of the project, so as encourage the entities to want the product.
Step 1:
Announcement to the entities: inform the entities about the project, the challenges it addresses and the expected benefits. You also need to make sure that you have the commitment and support of top management. Otherwise, the project is likely to fail.
Step 2:
Send a question list to the entities to gather for each entity or reporting unit the information necessary to build the conversion tables and the source files structures
