The migration tools of WebSphere Application Server Network Deployment, Version 6 support migrating the configuration of Network Deployment, Version 5.x to Network Deployment, Version 6.
Before you begin
This topic describes migrating a V5.x deployment manager to V6.Migrate V5.x of WebSphere Application Server Network Deployment to V6 before migrating the base nodes that comprise the cell. The deployment manager must always be at the highest release and fix level within a cell, to allow it to manage all nodes in the cell. In V6, the deployment manager has the capability to manage both V6 and V5.x release nodes (see Incremental cell upgrade for more information). This allows a cell to be upgraded to a new release one node at a time, with minimal impact to the applications that are running within the cell.
If you are migrating to a deployment manager on a remote machine, you can follow the steps outlined for an Application Server in Migrating V5.x of WebSphere Application Server to a V6 stand-alone Application Server on a remote machine. The steps are identical for a deployment manager.
Why and when to perform this task
Use the following procedure to migrate the deployment manager.
Steps for this task
stopManager.sh
If you have security enabled, specify the -user and -password parameters of the command.
You can migrate a V5.x deployment manager without stopping it, but it is not necessary for it to be running for you to migrate its configuration. The migration tools can retrieve all the configuration data while the deployment manager is either running or stopped. However, you must stop the V5.x deployment manager before you can start the V6 deployment manager that you are installing, so it makes sense to stop it now.

Result
After the deployment manager is upgraded to V6, each node in the cell may then be upgraded incrementally, one at a time. The following diagram illustrates a mixed-release cell containing a V6 deployment manager with both V5 and V6 managed nodes:
The migration tools migrate V5.x Samples to the V6 Network Deployment node, to support cell members at the V5.x level. If the migration did not migrate the V5.x Samples, a synchronization would remove the Samples from the V5.x nodes. After migrating all federated nodes to V6, the V5.x Samples remain in the configuration. You can remove the V5.x Samples at that time or replace them with the V6 samples.
