    11.5.9 to 11.5.10 Upgrade Approach

    marist89
      In anticipation of an impending maelstrom of regulatory changes, I want to upgrade my 11.5.9 EBS environment to 11.5.10 and at least have a hope of being supported. Upgrading to R12 is just not an option at this point, my users are overwhelmed by it. I know that's the best way to go, but it's not going to happen.

      I have an 11.5.9 environment on Solaris running on two tiers. The middle-tier serves Web & Forms. The DB Tier serves DB (10.2), CCM, and Reports.

      At the same time I upgrade, I want to move my EBS to Linux. I also want to change my configuration so that I am running Web/Forms/CCM/Reports all on the same tier and isolate the DB to it's own node.

      My general thought process was:
      1. Move the db from Solaris (10.2) to Linux (11.2) using a combination of (362205.1) and (557738.1).
      2. Install 11.5.10 on a new node (Linux) and just run the appropriate driver for the 11.5.10 patch against the db on Linux.

      Does this seem like a reasonable approach?

          No, as it is not supported -- You may log a SR to confirm with Oracle Support.

          You need to upgrade 11.5.9 to 11.5.10 (or 11.5.10.2) then migrate the database using export/import and the application tier node. Or, migrate the database then upgrade to 11.5.10/11.5.10.2 then migrate the application tier node.

            Hi, I was just curious how your 11.5.10 experience is turning out to be so far? Also, how far out would you say your plan to upgrade to R12 is - cause i have a similar situation and another consideration is that users will undergo 2 transitions fairly quickly - 11.5.10 and R12. In addition, R12.2 is around the corner and we'll be far behind in the journey. Please share your thoughts.
