Convert to S/4 with BW 7.5

Hello

We have a BW on HANA 7.5

We have a number of data sources that extracts data from our SAP ECC system.

These datasources(*) are not converted to ODP.

Will they need to be converted as part of the S/4 HANA migration or can they continue to be used after a migration to S4/HANA?

*Extractor and Generic Datasource

Thanks
