When upgrading Directory Proxy Server software to Java ES Release 5 you should take into account the following considerations:
In a deployment architecture in which there are multiple instances of Directory Proxy Server running on a single computer and all instances correspond to the same installed Directory Proxy Server image, upgrading the Directory Proxy Server image will require you to create new Directory Proxy Server instances.
In Release 4 deployment architectures involving Directory Proxy Server, an Administration Server was used to configure and manage Directory Proxy Server instances. In Release 5 the upgrade of Directory Proxy Server might entail deployment of the Directory Service Control Center, used to configure and manage Directory Proxy Server instances.
