Planning Your Upgrade to CA SiteMinder R12

CA SiteMinder R12 improves upon the functionality available in SiteMinder 6.x in several areas. In addition to fine-grained delegation through the new administration user interface, R12 improves directory mapping, adds support for web services, bundles federation support previously only available through the Option Pack and introduces fine-grained authentication capabilities. While these features warrant upgrade consideration on their own, an eventual end-of-life of SiteMinder 6.x will require an upgrade of your existing environment.

As you begin the process of upgrading your environment to R12, careful consideration is required to make sure the migration goes smoothly. New components like an application server are required and even the way policies are stored has changed with the addition of the extended policy objects. SiteMinder deployments provide mission critical functionality and the upgrade must be completed with minimal risk or downtime. To ensure a smooth upgrade path, ensure that you spend sufficient time planning for each phase of the move to SiteMinder R12.

As you look at your strategy for upgrading to SiteMinder R12, you need to consider the following:

Make sure that you have detailed information on each component of your SiteMinder environment
Understand your maintenance windows
Ensure that you have a good recovery and rollback plan
Map out the upgrade order of the components
