Cross platform migration to Oracle Cloud Infrastructure (OCI) is now certified for Oracle E-Business Suite Release 12.1 (12.1.3) with Oracle Database 19c.
E-Business Suite Release 12.1 Platform Migration from On-Premises to Oracle Cloud Using Transportable Tablespaces with Oracle Database 19c (MOS Note 2725557.1) describes the process of migrating an Oracle E-Business Suite Release 12.1 environment from on-premises to OCI and associated database services.
The overall process combines:
For optimum performance, the database migration process uses Transportable Tablespaces (TTS) with full transportable export/import, along with an option to further reduce downtime by utilizing incremental backup.
This strategy is required when you need to migrate an existing EBS environment across platforms, for example moving to OCI running Linux x86-64 from an on-premises platform of a different endian format, as described below.
The endianness of platforms can be checked by connecting to SQL*Plus as sysdba and querying the view V$TRANSPORTABLE_PLATFORM.
SQL> select platform_name, endian_format from v$transportable_platform;
On-premises database tier platforms certified for EBS 12.1.3 are:
Oracle Solaris on SPARC
HP-UX Itanium and PA-RISC
IBM AIX on Power Systems
Linux on IBM Z
Oracle Solaris on x86-64
Linux x86/Linux x86-64
This migration process requires the source database to be 11gR2 (188.8.131.52), 12cR1 (184.108.40.206), or 19c, with the target database 19c. The application tier EBS version will be the same on the source and target.
