How To Use Export And Import When Transferring Data Across Platforms Or Across 32-bit And 64-bit Servers (Doc ID 277650.1)

Last updated on FEBRUARY 11, 2021

Applies to:

Oracle Database Cloud Schema Service - Version N/A and later
Oracle Database Exadata Cloud Machine - Version N/A and later
Oracle Cloud Infrastructure - Database Service - Version N/A and later
Oracle Database Backup Service - Version N/A and later
Oracle Database Exadata Express Cloud Service - Version N/A and later
Information in this document applies to any platform.


This document provides the concepts how the export and import utilities can be used to transfer data, schemas, tablespaces, databases across platforms and across 32-bit/64-bit processor servers.

The document is limited to the usage of the Export and Import utilities, and does not give detailed information about the following upgrade or migrate procedures:
- upgrade of the Operating System (e.g. move from HP-UX 10.20 to HP-UX 11.0)
- upgrade of the hardware (e.g. move from 32-bit to 64-bit)
- upgrade of Oracle Software (e.g. move from Oracle9i to Oracle10g

For details about those procedures, see the Knowledge Browser in MOS:
- Tab:   Knowledge - Knowledge Browser
- Product:   Database - Installation, Upgrade and Migration.

In principle the information also applies to Oracle 11g. However, as of Oracle 10g, the Oracle DataPump (expdp/impdp) is preferred above the traditional exp/imp utilities.
Original Export is desupported for general use as of Oracle Database 11g. The only supported use of original Export in Oracle Database 11g is backward migration of XMLType data to Oracle Database 10g release 2 (10.2) or earlier. Therefore, Oracle recommends that you use the new Data Pump Export and Import utilities.
