If you’ve decided to upgrade your system to the newest version of DB2® keep in mind that it may require migration of your environment components.
Understanding what may go wrong in the installation is a big step in ensuring the upgrade is completed smoothly and successfully.
Below I have listed five high-level points to keep in mind while you’re upgrading your system to the newest version of DB2.

  1. Disk Space – The upgrade process will require additional disk space. Before beginning the process, make sure you have enough disk space to complete the process successfully. Here is a helpful reference for required disk space for DB2 v9.7 for Linux, UNIX, and Windows.
  2. Pre-requisites – As with any new installation, you will want to ensure that your system meets all the requirements for the upgrade. Check your software and operating systems and ensure that all other software interfacing with DB2 will be compatible. Refer to this article for the necessary prerequisites for successful installation.
  3. Test Environment – It’s always a good idea to upgrade DB2 servers in a test environment. This allows you to address any problems during the upgrade process and evaluate the impact of the changes on your system. Here is some information on test environments.
  4. Product Licensing – Before installing the new version of DB2, make sure you have licensed and registered your product with IBM®. Refer to this link for more information.
  5. Plan & Research – Give yourself time before the upgrade process to really research the newest version of DB2. Allow yourself to become familiar with the product and take time to explore the variety of new features it has to offer. Some of those features can be found here.
