Uprade from 11i to R12 with platform migration from 32 to 64

ACO Newbie
Currently Being Moderated
This is our current system:
apps 11.5.10.2
DB 10.2.04
OS RH Linux 3 32-bits
ebs Upgrade from 11.5.10.2( OS RedHead 32 bit) to 12.1.3 (OS 64 bit)

Target system
apps 12.1.3
DB 11.2.0.3
OS RH Linux 6 64-bits

The questions that I have are general about the approach which I need to follow:

1. Shell I upgrade everything in one (OS, DB, Apps) or split in stages:
- The limitations I have here are RH 6 64 bit is not certified with ebs 11.5.10.2 and DB 11G R2, therefore I don't have that option.

2. My intention is to mitigate the risk and I'm thinking to split the upgrade process into the following stages:
a. clone 11.5.10.2 to OS RH Linux 5 64-bits
b. upgrade DB to 11.2.0.3
c. upgrade apps to 12.1.3
d. clone 12.1.3 from OS RH Linux 5 64-bits to OS RH Linux 6 64-bits

Let me know your opinion about this.

    I am exactly in the same boat..

    Here is my source
    Suse 9 32 bit
    DB 10.2.0.5
    Apps 11.5.10.2

    However after several trials and errors this is how I have done my project
    a) Install Oracle Enterprise Linux 6.1 64 bit on a new server
    b) use rman with source as my test instance on a 32 bit server and target on 64 bit server with 11.1.0.7
    c) install EBS 12.1 using the upgrade option on 64 bit server
    d) upgrade database on 64 bit server to 11.2.0.2
    e) upgrade 12.1 to 12.1.3 on 64 bit server
    f) hold off with ias 10.1.3.5 till later

    of course the number of patches that I have installed are very very many.

    You cannot clone a 11.5.10.2 from 32 bit server to 11.5.10.2 on 64 bit server and you do not really need the full
    instance of the 11.5.10.2 on the 64 bit target server

    You only need the source database on the target server (64 bit)

    If you are installing R12.1 using the upgrade option it needs to connect to a Database on the same server
    R12.1 installs a 11.1.0.7 database --- so you basically need a database with your data as the source
    which is either 11.1.0.7 or earlier but 64 bit

    Hence I chose to have the source database as 64 bit 11.1.0.7

    Rman is able to connect from source database 32 bit 10.2.0.5 to target database 11.1.0.7 64 bit

    You said ---- clone 12.1.3 from OS RH Linux 5 64-bits to OS RH Linux 6 64-bits

    Cloning I do not think supports
    cloning from one server to another when the OS has changed
    so if you are planning to clone from Linux 5 to Linux 6 ...ummm...I dont think this is possible

    It is possible and supported as long as it is certified.

    Hello Hussein,

    My idea behind splitting the upgrade task in stages is to mitigate the risk and reduce downtime.
    If I understand correctly the process should be the following:

    Step 1
    1. Upgrade the database from 10gR2 to 11gR2 (11.2.0.3) by using Export/import notes on Applications 11i Database 11g
    - Release system to work with separated nodes DB on 64 bit machine and apps on 32 bit machine for a couple of weeks and prepare for the next stage.

    Step2
    2. Upgrade Apps to R12 by laying down R12 (12.1.1) on 64 bit machine
    3. Upgrade apps to 12.1.3 on the same mahcine.

    Thank you in advance for your confirmation.

    The above is not certified since I assumed in my previous update that you can migrate the database and upgrade to R12 directly without releasing the environment (which is on 11i) to the users. If you want to go with the above approach, use Linux 5 for the database tier node, then upgrade to R12 then upgrade the OS to Linux 6 as the last step.

    Thanks,
    Hussein
