As I know the following steps are recommended to move a local DS repository to a new database server:
1.Create a local repository on the new database server with Repository Manager;
2.Export the old repository to a file and import it into the new repository;
3.Use the Server Manager to delete the old repository entry, and then add the new one.
After performing these steps can we continue delta load of ODP datasources and openHUBs? Thank you in advance.
