How do I merge my population datasets from older versions of CAP-88 to CAP-88 Version 4?

The EPA recommends that you first try the Migration Utility that is a part of CAP 88-PC Version 4. When you first install Version 4, you must do two things: First, install the code, and, second, run the Migration Utility—the second step will create data folders for Version 4and transfer any Version 3 data to your updated CAP-88 software. If you have already installed Version 4, run the Migration Utility by going to the “Tools” drop down menu on the main screen.
