Read the 9.9 product readmes, including the 9.9 readme for the Software AG Infrastructure, available on the Software AG Documentation website. The product readmes contain this information:

Critical information, known issues, fixes, resolved issues that had not been rolled into fixes at the time of the release, and usage notes for your products.

Changes to product behavior, services, parameters, properties, APIs, documentation, and terminology. This information is especially important because you might need to modify product files or assets after migration to accommodate the changes.

Read the product release notes; the release notes provide information on new functionality. Read the information for every release for your old release + 1 through the 9.9 release.

Perform the tasks in this guide in the exact order in which the tasks are presented. The task order is critical because your products have many inter-dependencies, including a shared infrastructure.

Do not start any 9.9 products before the instructions in this guide tell you to do so, or your database components could become corrupted.

Perform the tasks in this guide for all upgrade paths unless the guide states that a particular task is required for certain upgrade paths only.

In the 9.7, 9.8, and 9.9 releases, the webMethods Broker release number is still 9.6 and is the same release that was available with the 9.6 release. Even though the release is the same, you must still perform the tasks described in this chapter and this guide for webMethods Broker.
