I have a client that wants to migrate their data from Adabas on a mainframe to Oracle on a Windows Platform. They want to decommission an application written in COBOL on the mainframe and create a new web based application that will work with the Oracle database. We have designed to ETL to get the data out of Adabas and into Oracle.
The client now wants to keep the Oracle DB and the Adabase DB in sync for several months so that they have confidence that if they want to go back to using the mainframe systems they can and all the data is in sync. What is the best way to do that? Is there a bolt on for Adabas and Oracle that will keep both in sync?
The other issue is that the client only has a production Adabas and no development or test environment so we cannot break it during development thought please?
