Migrating InfoScale products to support IPv6/dual-stack

Each new InfoScale product consists of one or more components. Each component within a product offers a unique capability that you can configure for use in your environment.

Most of the components that make up the InfoScale products are dependent on each other for various functions. Therefore, when you migrate those components to support IPv6 or dual-stack, you must follow a certain sequence.

InfoScale products can be installed and configured in several ways depending on the requirements of your IT environment. You can choose to deploy only those components that provide the features that you need to use. The following topics describe how to migrate all the components that the InfoScale product suite comprises. You can focus on the migration tasks for the components that are configured in your environment and ignore the rest.

For example, the following figure depicts the basic implementation workflow for InfoScale Enterprise. In addition to these components, your environment may also have components like Oracle RAC, ASM, and so on.

Figure: Basic implementation workflow for InfoScale Enterprise

Basic implementation workflow for InfoScale Enterprise

Note:

The sequence in which you migrate the InfoScale components is different than the sequence in which they are implemented.

To migrate InfoScale products to support IPv6/dual-stack

Follow this sequence when you migrate the InfoScale components so that their dependencies are addressed successfully. If some of the components listed here are not present in your deployment, proceed to migrate the next component in the sequence.
