Updated Platform Migration Procedures Certified for EBS 12

source_target_migration.png
We are pleased to announce the certification of the Platform Migration Methodology for Oracle E-Business Suite Release 12.  The existing documentation has been updated to be generic for all Release 12 versions.

The platform migration process provides a way to quickly and easily move an existing Oracle E-Business Suite application tier to a different platform, allowing you to utilize different hardware for the application tier.

The migration utility retains the exact Oracle E-Business Suite patch level, so that no APPL_TOP or database synchronization is necessary.  This also allows you to retain many customizations.

The existing procedure available for 12.0 has been optimized and modified for all Release 12.x versions. You can find more details in the following document available in My Oracle Support:
Some additional considerations
  • This migration methodology requires at least E-Business Suite version 12.0.4 for Release 12.0 and 12.1.1 (or higher) for Release 12.1.
  • This methodology applies to the Application Tier (middle tier) only.  The database tier is not covered by this process.
  • Migration to Windows-based target servers is not supported at this time
  • The platform migration procedure is not supported with Linux running on IBM System z (Source or Target) at this time.
Your feedback is welcome

We're extremely interested in hearing about your use cases and your experiences with these updated procedures. Please post a comment here or drop us a line with your thoughts.

Ravi,
The procedure posted on this document (438086.1) applies only for the Apps Tier. I would suggest you look at the Server Technologies specific documentation or contact Oracle Support for more details.
Thanks!

Hi Steve,

We are currently on HP_UX RISC 11.23 and planning to migrate HP_UX Itnanium 11.31. The document suggesting to install 12.1.2 tech stack on new hardware and copy APPL_TOP and some other comn_top files. But we are not getting 12.1.2 media pack and it forces us to install 12.1.1 and upgrade to 12.1.2 .

Would like to know your suggested approach for our requirement.

Thanks!
Thy

Thy,
There is no specific 12.1.2 Rapid Install Media for HP. The only one available so far for HP is 12.1.1. However, part of the process is to obtain a patch from Oracle to get the latest version for binary objects under the APPL_TOP (Section 2, Step 1b and Step 8). This will keep the same version you had in the source.

Additionally, on Section 2, Step 6 of the migration document you have to install the technology stack included in 12.1.1. If you had applied patches in the Application Tier Oracle_Homes (10.1.2, 10.1.3) you will have to apply them in the new platform as well to keep the same component versions (Section 2, Step 10).
If you need further assistance or clarifications I would suggest you consult with Oracle Support so they can assist you closely in the process.
