apply cdc to existing data warehouse
seeing as no one has helped me with this i'll answer myself to help anyone who is looking at the same thing.  It looks as if to enable CDC on an existing warehouse you need to do this on a table by table basis, recommending capturing all the ETL in package per table.  Also, it is recommended to enable CDC state per table to avoid conflicts.  Recommended approach would be --> enable CDC on source DB.  Transfer incremental loads to staging DB or schema inside DWH.  Incrementally load records to Dimensions and Facts. Every example i can find on net is for one table, which is fairly useless... be much appreciated if someone can find a CDC example for multiple tables...
