Map Scenario 3: Flexible Management: 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 to version 8.0, you must first migrate the administrative agent.

Before you begin

Supported configurations Supported configurations:

This topic 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.

About this task

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 to Version 8.0. 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 8.0 admin agent console using the WC_ adminhost or WC_ adminhost_ secure ports as defined in the new Version 8.0 admin agent's serverindex.xml file. Additionally, the Version 7.0 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 8.0 and previous releases.

For migrating the managed base application server in a flexible management environment, ensure that the node names are the same on Version 8.0 and previous releases.

Avoid trouble Avoid trouble: Ensure that your setting for the maximum number of open files is 10000 or greater. If the number of open files is too low, this can cause a variety of migration failures.gotcha

Procedure

  1. Install WebSphere Application Server Version 8.0
  2. Create the target administrative agent profile
  3. Ensure that all the "In Progress" jobs are completed on the managed profiles
  4. Stop polling the job manager
  5. Run the WASPreUpgrade command from the new WebSphere Application Server install root bin directory
  6. Verify the console output and the WASPreUpgrade logs for success, warnings, or failure
  7. Run the WASPostUpgrade command from the new WebSphere Application Server install root bin directory
  8. Verify the logs for success
  9. Start the Version 8.0 administrative agent
  10. Migrate managed base application servers
  11. Troubleshooting

Results

You have migrated an administrative agent profile and its associated managed base application servers from WebSphere Application Server Version 7.0 to Version 8.0 using the migration tools. You can stop the Version 7.0 administrative agent and you can assign the Version 7.0 ports to the Version 8.0 administrative agent.
