Upgrade R12.0.6 to R12.2.5
Hi All,
Source OS : RHEL 4.6
Apps : R12.0.6
DB : 10.2.0.3
Target : RHEL 6 / RHEL 7.
Since both DB and Apps of our Source version is not certified with RHEL 6 / RHEL 7 and the Hardware supported for RHEL 6 and Above. We cannot use our New Hardware for Upgrade Process.
The approach we decided is :
1. Prepare the server which is same as prod - Preprod
2. Clone the Prod to Pre Prod
3. Upgrade Database to 11.2.0.4 ( Database Preparation Guidelines for an Oracle E-Business Suite Release 12.2 Upgrade (Doc ID 1349240.1) )
4. Upgrade Application to R12.2.3 (Release 12.0 and 12.1 to 12.2 (Part No. E48839)
5.Upgrade Application to R12.2.5
6. Clone r12.2.5 to New Hardware
