Update the Source Schema
In the next section, your source database is updated with a delta schema file that results in a QAD Standard Edition schema updated to the current service pack level. First an existing schema file is selected, copied, and modified to include your domain.
Depending on your source version and whether you have taken advantage of structure files to optimize your data files on disk with later Progress versions, you have two choices of delta file for your source version. Both types of delta .df file are located in TVInstallDir\ inplace\progress.
Storage Areas
In the \storagearea subdirectory are delta .df files that you can edit to optimize your new schema to specific-sized locations on your disks.
Schema Area
In the \schemaarea subdirectory are delta .df files that place the new schema into the default schema area used for non-structured database files.
Warning Make sure you know the correct version and release for your source database. Using the wrong .df file will result in errors.

The file path displays in the Find Data Definition File screen. Choose OK to create the new delta file for your environment.
