Another thought is to use DTS to handle at least some of the transfer for you. SQL Server's DTS (Data Transformation Services) package will be able to connect to Oracle, create the table structure and import the data for you. You are on your own as far as foreign keys and primary keys, etc. But something like ERwin could help you out with that.

DTS is great for simple data loads, not sure how complicated your migration is, but its something to look into.

Good luck!

Babu - Congratulations on the project! Is this database especially large or are you facing severe restrictions in terms of the amount of time the data is unavailable to your users? Are there any unusual objects in SQL Server that will be difficult to create in Oracle? I think Oracle provides a migration tool, but I haven't used it. Usually I follow a procedure such as:

1. Create objects in Oracle.
2. Dump data from SQL Server to a flat file.
3. Load the data with SQL*Loader.
4. Verify the data, application.
5. Prepare for production cut-over.
6. Truncate Oracle tables.
7. Dump data from SQL Server to a flat file and load with SQL*Loader.
8. Shut down SQL*Server.
9. Verify application is ready to go live.

Hi Listers,

We are planning to migrate one of our SQL Server database to ORACLE 9i. Please point me to the checklist and required documents. Any help in this regard very much appreciated.
