Migrating Oracle E-Business Suite across platforms (different Endian format)
For some customers, it might be the case that the source and target platforms have a different endian format.
Oracle E-Business Suite cross-platform migration using Oracle Transportable Tablespaces
Application tier migration
Cross-platform migration of Oracle E-Business Suite application tier is detailed in the Oracle Support Notes that follow.
Cross-platform migration of Oracle E-Business Suite application tier process (high level):
-
Prepare source and target systems for migration.
-
Run
adpreclone.pl
on the source system. -
Generate a customer-specific manifest file and upload to the MyOracleSupport
website. -
Copy
APPL_TOP
,COMMON_TOP/java
,COMMON_TOP/webapps
, and so on to the target. -
Copy the source context file to the target.
-
Generate the target context file using the pairs file and source context file on the target.
-
Run Rapid Install Wizard with
-techstack
option to install technology components. -
Run AutoConfig on the target.
-
Apply customer-specific patches (obtained from the manifest upload procedure).
-
Review components and technology stack patchset level.
-
Regenerate file system objects.
-
Clean nodes.
-
Run AutoConfig.
-
Update printer and workflow settings.
-
Start all services on the target.

Database migration
Transportable Tablespaces is an Oracle database feature that provides a faster way to move bulk data from one database to another, independent of the OS of the source and target. The Cross-Platform Transportable Tablespaces (XTTS) provides functionality in distributing data and database migration specifically across platforms of different endian (byte-ordering) formats.
This migration method is particularly suited for very large databases where the relative size of metadata is small compared to the data.
Refer to Oracle Support Note #2674405.1
You can also perform incremental data transfer using Oracle Transportable Tablespace.
For details, refer to Oracle Support Note #2471245.1
Incremental backup is supported only for the same platforms, and from big endian platforms to Linux OS only. Following is the typical flow for migration using incremental backups when using XTTS.
