-25603: Error processing IMPORT in PAGE Format. Loader versions used for EXPORT and IMPORT differ (EXPORT <version>, IMPORT <version>) 

Explanation:

You have attempted to re-import data that was exported in the PAGES format, which was provided by the database. Here the Loader detected that the version of the Loader used for importing data is different from the version of the Loader with which the data was exported. To ensure that the data is re-imported correctly, the version of the Loader has to be the same for importing and exporting of the data in the PAGES format.

User Response:

Start the import using the same version of the Loader used for the export.
