RMAN Restore a 32 bit Database to 64 bit - Description and Example (Doc ID 467676.1)

Last updated on SEPTEMBER 06, 2017

Applies to:

Oracle Database - Enterprise Edition - Version 9.2.0.1 and later
Information in this document applies to any platform.

Goal

Restoring a 32Bit (with 32 Bit Oracle Binaries) RMAN backup on 64Bit Operating System (with 64 Bit Oracle Binaries) - same Operating System Platform !

On a given platform, backups are interchangeable between 32 and 64 bit versions of Oracle. 

However, simply restoring a backup that you took on a 32-bit system, onto a 64-bit system,
is not sufficient to migrate your database from 32-bit to 64-bit.

You must also follow all of our other migration procedures, such as re-compiling your pl/sql.

Same goes for a backup taken on 64-bit Oracle and restoring with 32-bit Oracle.
