    Unanswered: Upgrade DB2 instance from WSE to ESE

    I have a DB2 UDB Server V8.1 WSE for AIX. Now, I want to upgrade the DB2 instance from WSE to ESE (64-bits).

    It seems to me that the command "db2iupdt" can change the instance from 32-bits (WSE) to 64-bits, but this command does not have option to change the instance from WSE to ESE.

    So, do I need to drop the existing WSE instance and then recreate the instance (by db2icrt) with the instance type (ESE) and wordwidth (64 bits)?

    Pls advise.

    Arrow Distinction

    Hi Wong

    As far as I'm informed the only distinction between
    WSE and ESE is the amount of processors allowed

    So the way to go to ESE is buying a license for more
    than 2 processors and using the db2licm command to
    update your licenses

    You can use the -? switch to see options

    After OR before that you can update your instance or create
    a new one concurrently for test purposes - you can run 32 and 64
    bit instances on the same machine

    Good Luck
