Delta Timestamps in ECC when upgrading BW3 to BI7



We are about to do a technical upgrade of our BW 3.1 system to BI 7.0. BW currently contains a large volume of CO-PA Sales and HR Payroll data that are managed through Delta extractions from ECC6.

When BW has upgraded to BI, can we realistically expect that Deltas will continue without any problems.

I understand that the CO-PA time/datestamp for deltas is stored in Table TKEBWTSN and that the HR Payroll time/datestamp for deltas is stored in Table hrms_bw.

Should we backup these tables before the upgrade, so that if the first delta extracts fails, it would be possible to rerun them after updating these tables.

Are there any other precautions that we could take? Unfortunately our development BI system is not set up for Deltas from an ECC source, so we are unable to properly test.

Any suggestions or feedback on managing Deltas during and postupgrade to BI7 would be greatly appreciated.
