Before migrating any cluster
node to WebSphere Process Server 6.0, ensure that every node in
your cluster has WebSphere Business Integration Server Foundation
5.1 or 5.1.1 installed.
The Deployment
Manager of WebSphere Process Server 6.0 is not compatible with previous
versions of Server Foundation, including 5.1 and 5.1.1. Therefore,
the static configuration
data of the unmigrated 5.1 or 5.1.1 managed nodes cannot synchronize
with the Deployment Manager until after the managed
node has been migrated. Migrating a cluster requires strict adherence
to the following steps.
- Install WebSphere Application Server 6.0 on every
workstation that has a WebSphere Business Integration Server Foundation
node in the cluster to be migrated.
- Use the profile
creation wizard to create a profile on each WebSphere Application
Server 6.0 installation. For Deployment
Manager nodes, create a deployment
manager profile (specify the same cell and node name of the 5.1
or 5.1.1 Deployment Manager). Otherwise create a stand-alone
profile (specify the same node name as the 5.1 or 5.1.1 managed
node).
- For each node, install WebSphere Process Server 6.0 in
the same directory as WebSphere Application Server 6.0. Ensure that
the profile
is augmented with WebSphere Process Server files. Do not start the
6.0 server.
- From the 5.1 or 5.1.1 Deployment
Manager administration console, disable
the File Synchronization Service for each 6.0 node agent
and then restart every node
agent in the cluster.
- Stop the 5.1 or 5.1.1 Deployment
Manager.
- Migrate the 5.1 or 5.1.1 Deployment
Manager to WebSphere Process Server 6.0 (follow instructions provided
for Migrating a cluster from WebSphere Business Integration Server Foundation to WebSphere Process Server 6.0).
- Start the 6.0 Deployment
Manager. The 6.0 Deployment Manager must be started when you migrate
the managed
nodes.
- To maximize application
availability while migrating, leave half of the 5.1 or 5.1.1 managed
nodes in the cluster running. For the other half of the managed
nodes, perform the following migration steps for each node:
- Stop all servers on the node and the node
agent.
- Migrate the node (follow the instructions provided
for Migrating a stand-alone version of WebSphere Business Integration Server Foundation to WebSphere Process Server 6.0).
- Stop the remaining 5.1 or 5.1.1 managed nodes. Stop all
servers on the node and the node agent.
- Start the 6.0 managed nodes that were migrated in 6
- Start the node
agent and all servers on the node.
- From the 6.0 Deployment
Manager administration console, enable
the node agent File Synchronization Service of the 6.0 migrated
node, and then restart the node agent.
- Verify that the node agent, servers, and enterprise
applications running on the server start successfully.
- Migrate the remaining 5.1 or 5.1.1 managed nodes (these
nodes should be in the stopped state):
- Migrate the node (follow the instructions
provided for Migrating a stand-alone version of WebSphere Business Integration Server Foundation to WebSphere Process Server 6.0).
- Start the node
agent and all servers on the node.
- From the 6.0 Deployment Manager administration console,
enable the node agent File Synchronization Service of the
6.0 migrated node, and then restart the node agent.
- Verify that the node agent, servers, and enterprise
applications running on the server start successfully
Once all nodes of the cluster are migrated, the migration
is complete.
