    Upgrade from Siebel to Siebel


      Hi All,


      Current Siebel environment is in Windows 2003 Server (32-bit) and planning to upgrade to Siebel in new OS Windows 2008 R2 Server (64-bit) with Open UI enabled. I have gathered all required information for upgrading this whole environment.


      - Siebel apps will still be 32-bit application.

      - Siebel enterprise can be installed on 64-bit with IIS 7.5 (with 32-bit compatibility)


      I plan to do this:

      a. Take a clone of existing Siebel database and name it "UpgradeDB"

      b. Install Siebel 8.1.1 in the new Windows 2008 R2 Server (64-bit)

      c. Install Siebel tools/Client 8.1.1 in windows XP (32-bit)

      d. connect to the cloned database "UpgradeDB"

      e. Apply Siebel patch upon existing 8.1.1

      f. Execute IRM

      g... rest of the steps as mentioned in the bookshelf.


      My question is: Should I install all the patches after 8.1.1 upto to get a successful upgrade to


      Can I directly install upon Siebel 8.1.1?


      If the plan above is not correct, please help!

          Hi Suchitra,


          All the enhancements and fixes from 8.1.1 to will be available with

          Installing the patch and executing IRM (If you intend to use Open UI and new features included from the Siebel CRM version innovation pack)

          are sufficient to do successful upgrade.

          Instead of cloning and connecting to the DB you could create a restore point and use it when needed. Always keep a level 0 cold backup before making any changes to the database

          as part of pre-upgrade tasks.
