    Unanswered: Upgrading DB2 ESE to 10.1


    We are using DB2 9.5 and 9.7 in two of the servers as a DB for application RAM. Now we plan to upgrade the same to the latest release which of version 10.1.

    Note: We do not have a dedicated administrator.

    In the past for one of the instance we have restored the backed up db and during restoring itself the DB got upgraded.

    Here the case is different - we have an existing DB2 9.7 version

    My question is - Can we directly run the DB 10.1 setup and should we uninstall the existing one and install the new one.

    From application side I believe we would require the DB backup to be taken and restore it to the new DB.

    Follow the advice at the db2 migration roadmap portal

    For V9.7 and V9.5 you can upgrade a database directly to V10.1

    I always prefer to install the new version (or new fixpack) to a new filesystem/directory, because that makes back-outs much easier, and the installation work can be completed separately without downtime in advance. The actual upgrade can happen later.
