Upgrade Apps from 11.5.10.2 to 12.1.3 and migrate platform from AIX 5.3 to OEL 5
Hi,
We are in process of deciding the Upgrade approach for Apps 11i to R12.
I have doubt on Apps Upgrade and Migration apat.
Current version:
---------------------
Apps : 11.5.10.2
OS : AIX 5.3
Target expected:
--------------------
Apps : 12.1.3
OS : OEL 5
Method 1:
==========
1. Upgrade 11.5.10.2 to 12.1.3 on AIX 5.3
2. And Then Migrate 12.1.3 from AIX to OEL 5
Method 2:
=======
1. Using Rapidwiz Install new Application tier R12.1.3 on OEL 5
2. Upgrade 11.5.10.2 to 12.1.3 on OEL5 using the upgrade steps.
We are clear that method 1 will work as oracle standard.
but We are not sure whether Method 2 is the correct approach and whether this wiill work? i.e can we do upgrade and paltform migration in a single step by laying down the new application tier on the target platform as part of the upgrade.
