Way to migrate large database other than export/import

Is there any other way apart from using export/import for migrating the database between different platforms? Export/import is taking more time for TB databases.

Export and import may not be a valid option for migrating a database that is very large, i.e., in the terabyte range. Depending on your environment, there is the option of using transportable tablespaces, but you must be using 10g to take advantage of the new features. The process, at a high level, is as follows:

You install Oracle 10gR2 on server, upgrade your database in place and then use the new cross-platform transportable tablespaces feature to move your database to your new server. If you are migrating a database cross-platform, query the view V$TRANSPORTABLE_PLATFORM to see supported platforms and what their endianness is. If your source operating system is big endian but the target system is little endian, there is an additional step involved to convert the tablespaces being transported on either the source or target side.

To read more about the cross-platform transportable tablespace feature, download the Oracle Database Administrator's Guide 10g (release 10.2) from Oracle Technology Network.

You should also review the Oracle Database 10g Release 2 (10.2) Upgrade Guide.
