Migrating an administrative agent profile and its registered set of managed base application servers
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 later to Version 9.0, you must first migrate the administrative agent.
Before you begin

This article is about profile configuration migration. To migrate your applications to the latest version, use the WebSphere® Application Server Migration Toolkit. For more information, see the Migration Toolkit on WASdev.

About this task
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 9.0 admin agent console using the WC_ adminhost or WC_ adminhost_ secure ports as defined in the new Version 9.0 admin agent's serverindex.xml file. Additionally, the Version 7.0 or later 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 9.0 and previous releases.

Procedure
Results
You migrated an administrative agent profile and its associated managed base application servers from WebSphere Application Server Version 7.0 or later to Version 9.0 using the migration tools. You can stop the Version 7.0 or later administrative agent, and you can assign the Version 7.0 or later ports to the Version 9.0 administrative agent.
