best way to migrate a windows forms application from sql server to oracle

Question

I looking for a best way to migrate a Windows Forms application from MS SQL Server to Oracle. The table schema is recreated in oracle allready and the data was copied into Oracle tables. The App uses ADO.NET Datasets to access the DB. So, should I just kind of replace all references to SqlDataAdapter with OracleDataAdapter, SqlConnection with OracleConnection etc. in the autogenerated DataTableAdapters code, or is there is some other way to make the existing dataaccess code work with Oracle?

Have a look at my answer here: MVC3 and Entity Framework

in fact this logic of layering and separation of concerns applies to MVC, WinForms, WPF, SL and so on... in such layered stack only the DAL (Data Access Layer) is impacted and needs to be updated, everything else stays the same.

my suggestion is to make such DAL class library separated from anything else and in there, as you mentioned, you should replace SqlConnection and SqlCommand with the Oracle ones.
