A new utility named CloneDBC is included with the latest Advantage OLE DB Provider (version 188.8.131.52) which replaces the DBCConvert.prg which was included in previous versions. The CloneDBC utility creates an Advantage Data Dictionary which contains references to the same tables as a FoxPro Database Container. This makes it easier for developers working with FoxPro data to access it through Advantage.
This short screencast, about 7.5 minutes, highlights the features and limitations of the utility. It also walks through the conversion of a sample DBC. You can get more information about CloneDBC in this announcement.
