    Unanswered: uninstalling DB2

    Hi all,
    I recently migrated from DB2 V8.2 to V9.1. Can I use the installp -u db2_08_01 command to uninstall V8.2? Does it have any effect on the current DB2 V9.1 instance? Do I need to verify or backup any files before I run this command.Below is db2level,db2ls and list of db2_o8 files.Is there a cleaner way to uninstall other than installp command?

    DB2 9.1 install path - /opt/IBM/db2/V9.1/instance
    DB2 8.2 install path - /usr/opt/db2_08_01/instance


    db2inst1=> db2level
    DB21085I Instance "db2inst1" uses "64" bits and DB2 code release "SQL09016"
    with level identifier "01070107".
    Informational tokens are "DB2 v9.1.0.6", "s081211", "U823469", and Fix Pack
    "6a".
    Product is installed at "cd".

    db2inst1=> db2ls

    Install Path Level Fix Pack Special Install Number Install Date
    --------------------------------------------------------------------------------------------
    /opt/IBM/db2/V9.1 9.1.0.6 6a Sat Apr 18 00:56:36 2009 CUT

    To remove DB2 products from your UNIX system:

    Log in as user with root authority.
    Mount the DB2 Version 8 product CD-ROM.
    Run the db2_deinstall -n command from the root directory of your DB2 Version 8 product CD-ROM. The -n parameter makes pkgrm non-interactive. The -n parameter is only on System V (Solaris).
    This command will remove all DB2 products from your system.

    There are alternative methods for removing DB2 products from your operating system. You may employ one of these methods if you only want to remove a subset of DB2 products from your system. Alternative methods for removing DB2 products include:

    AIX
    You can use the System Management Interface Tool (SMIT) to remove some or all DB2 products. If you use SMIT to remove DB2, DB2 Version 8 products can be identified by their prefix of db2_08_01. You can also remove all DB2 products from AIX systems using the installp command by entering installp -u db2_08_01.


    Removing v8 doesn't have any effect on v9.
