Migrating From ODBC to ADO

I have the task of migrating a Delphi ODBC/BDE application to ADO and have
not gone down this path before.  I'm also new to ADO.   This application
utilizes Woll2Woll components quite extensively and what I'm looking for is
a highly level checklist of the steps to follow when migrating an
application from ODBC (particularly when using woll2woll components) to ADO.
The database server is SQL Server 7.

Would also appreciate any tips and warnings from others who have done
something similar
to this recently.

Thanks in advance.
