Upgrade and coexistence considerations

Cannot upgrade an existing installation to the current version

You cannot upgrade an earlier version of Rational Application Developer for WebSphere® Software, such as version 8.5.x or version 8.0.x, to the current version.

Coexistence within a package group

When you install each product package, you select whether you want to install the product package into an existing package group or whether you want to create a package group. IBM® Installation Manager offers only products that are designed to share a package group and meet version compatibility and other requirements. If you want to install more than one product at a time, the products must be able to share a package group.

Any number of eligible products can be installed to a package group. When a product is installed, the product functions are shared with all of the other products in the package group. If you install a development product and a testing product into one package group, when you start either of the products, you have both the development and testing functions available to you in your user interface. If you add a product with modeling tools, all of the products in the package group have the development, testing, and modeling functions available.

Coexistence between package groups

Multiple instances of a product package can exist on the same computer and they are automatically installed into separate package groups. The product packages can be at different versions or fix levels.

If you update a product package, you update only that instance of the product.

Coexistence with earlier versions of product

This version of Rational Application Developer for WebSphere Software can coexist with earlier versions of the product that are installed on the same computer.
