Assess applications in your environment before you upgrade

Preparing to upgrade provides an opportunity to review your existing applications and clean up your source environment.

For example, you might have many applications in your environment. However, it is not uncommon to find that a number of applications are not used or no longer meet your requirements.

Assessing your applications is a useful exercise because it can reduce the number of applications to consider during an upgrade.

An audit of your existing applications can include the following tasks:

After your audit is complete, you can create an upgrade plan.

Guidelines when upgrading your operating system

You might want to consider the following guidelines before you upgrade to a later version of the operating system on the computers where IBM Cognos BI is installed:
  • Check the IBM Software Product Compatibility Reports page (www.ibm.com/support/docview.wss?uid=swg27042164) to ensure that the IBM Cognos BI version supports the version of the operating system you are thinking of moving to.
  • Ensure that the third-party software that is used by IBM Cognos BI is supported on the proposed operating system version. Third-party software would include components, such as database and database drivers, application servers, web servers, and browsers.
  • Determine whether you must recompile IBM Cognos BI SDK applications.
  • Determine whether you must re-create web deployments, which include web archive (.war) files and enterprise archive (.ear) files.
