Jeffrey,
The cheap and most effective solution would be to use XML.
If you have the DDL for all of the objects in the database, you can just duplicate it on whatever RDBMS engine you want, and then, extract the data, table per table into XML files from the target server, and then load the files into the target server.
Otherwise, if you are going to do this in an ongoing fashion, then, use SAP Replication Server. The best asynchronous, real time, heterogeous replication solution in the industry, exploited with a great deal of success by many critical mission financial applications with global topologies and sub second latency.
My two cents.
I hope they help.
Regards,
Jean-Pierre
