ER Diagram is an Entity-Relationship Diagram. Essentially it is a standard way to model Databases before UML. Truthfully most people still model databases using ER Diagrams instead of using UML. I would also say that ER Diagram would be the best answer to question since a list of gui objects is useless, application code is irrelevant, and application design is what they plan to change in the first place (going from a 2-tier to an n-tier). I would want a list of use cases or at least a requirements list but neither of these are options, therefore I would be forced to go with the ER Diagram.
