Administrative agent profiles manage multiple base application servers in environments such as development, unit test or that portion of a server farm that resides on a single machine. Before you can migrate managed base application servers from Version 7.0 or above to Version 8.5, you must first migrate the administrative agent.
This article is about configuration migration, such as migrating deployment managers and federated nodes in a network deployment environment. The Application Migration Toolkit for WebSphere Application Server provides support for migrating applications from previous versions of WebSphere Application Server to the latest product version. For information about migrating applications, read more about the Application Migration Toolkit.

You can migrate administrative agent profiles and the registered set of managed base application servers from Version 7.0 or above to Version 8.5.
This task describes how to use the command line tools to migrate an administrative agent and its associated set of managed base application servers from WebSphere Application Server Version 7.0 or above to Version 8.5. A base application server becomes managed when it is registered with a single administrative agent. An administrative agent may manage one or more base application servers and must be at the same release level and on the same machine as the base application servers it is managing. Because of this restriction, the administrative agents on both the old and new release run simultaneously until all managed base application servers are migrated. The migration of an administrative agent does not bring forward its old port values, however, all other configuration data is migrated. Access the Version 8.5 admin agent console using the WC_ adminhost or WC_ adminhost_ secure ports as defined in the new Version 8.5 admin agent's serverindex.xml file. Additionally, the Version 7.0 or above administrative agent must not be shut down or disabled during this procedure. For migrating the managed base application server in a flexible management environment, ensure that the node names are the same on Version 8.5 and previous releases.

You migrated an administrative agent profile and its associated managed base application servers from WebSphere Application Server Version 7.0 or above to Version 8.5 using the migration tools. You can stop the Version 7.0 or above administrative agent, and you can assign the Version 7.0 or above ports to the Version 8.5 administrative agent.
