Problem: Apps upgrade to R12 and Platform migration to Linux in one go



Symptoms:
We are currently using EBS 11.5.10.2 RUP7 with 11G R2 database in a split configuration i.e. Database is on one node (HP-UX Itanium), APPS and concurrent manager on another node (HP-UX PA-RISC). Now we are planning migrate the apps tier to Linux and upgrade to R12 using the following highlevel approach.


1. Since the Database is already in latest release and no plans to migrate to new hardware, we will not perform any DB upgrade and platform migration activities for database
2. Perform R12 pre-requisites and pre-upgrade activities like

Apply 11i.AD.I minipack
Run the Upgrade Manual Scripts (TUMS) utility
Apply pre-requisite patches, if any
Gather schema statistics for CBO

3. Install the R12 Apps on the target system using rapidwiz without upgrading the source 11.5.10 on PA-RISC
4. Perform upgrade
5. Finish the upgrade
6. Post-upgrade tasks

The same approach is published by HP for "Oracle E-Business Suite Release 12 upgrade and platform migration guide: HP 9000 to HP Integrity" and "Oracle E-Business Suite Release 12 upgrade and platform migration guide: Tru64 UNIX to HP-UX Integrity"

I would like to know the above approach (APPS Upgrade and Platform Migration in One go ) is certified and supported for PA-RISC to Linux migration?





Solution:


You don't need to perform the Release 12 upgrade on the current server, then migrate to LINUX. You can directly lay down the file system on the LINUX machine, then continue with the upgrade steps as per the upgrade manual.

Also, please ensure your target box meets all the requirements as per:

Article-ID: Note 761564.1
Title: Oracle Applications Installation and Upgrade Notes Release
12 (12.1.1) for Linux x86

or (if the target is on 64-bits):

Article-ID: Note 761566.1
Title: Oracle E-Business Suite Installation and Upgrade Notes
Release 12 (12.1.1) for Linux x86-64

When running rapidwiz for the first time, please ensure you specify your current database details. For more information, please visit:
