Tds Utility from 2005 to 8.8

Dear All,

I am going to upgrade the system from SAP 2005 to 8.8 but i have doubt about how my table structure is going to upgrade & what is pre-requasite before upgrade.

As per my Knowledge SAP provided some query to transfer the TDS data 2005 to 8.8.

Please provide if anybody have this query & Provide TDS Utility also.

Waiting for immediate reply from your side.

Regards
