In the original system, you can restore 3.x DataSources from DataSources that were migrated using the standard method (SAP source system, file, DB Connect). With a transport operation, you restore the 3.x DataSource in the target system as well.
You can restore the 3.x DataSource manually or by automatic data flow migration. For more information about automatically migrating and restoring data flows, seeMigrating Data Flows.
Only use this function if unexpected problems occur with the new data flow after migration and these problems can only be solved by restoring the data flow used previously.
You can also use this function to revoke a replication to the incorrect object type (R3TR RSDS).
For file source system and DB Connect: You exported and archived the relevant 3.x objects when migrating the 3.x DataSource.
