Migration involves copying the configuration from a previous
release of WebSphere Virtual Enterprise into WebSphere® Application Server, Network Deployment, Version 8.5.
Before you begin
To migrate from WebSphere Virtual Enterprise V6.1.1 or
V7.0 to
WebSphere Application Server, Network Deployment,
Version 8.5.x, you must have
one of the following versions:
WebSphere Application Server, Network Deployment, Version 8.5.5.2
or later
WebSphere Application Server, Network Deployment, Version 8.5.5.1
with the latest interim fix
- WebSphere Application Server, Network Deployment, Version
8.5.0.2 or later with the latest interim fix
If you are migrating from WebSphere Virtual Enterprise
Version 6.1.1, you must update WebSphere Application Server to Version 7.0.0.x
before you can migrate to Version 8.5.x. After you update the product,
start all servers on all nodes to incorporate the changes, then stop
all servers.
For more information about these versions, see Latest fix packs for
WebSphere Application Server.
Note: To complete this task, you must have the user ID and password
for your WebSphere Application Server, Network Deployment, Version 8.5 environment.
Avoid trouble: If you run
VEUpgrade with no parameters to get command line help, existing migration
logs are overwritten. To retain the migration logs, copy the logs
to a backup directory.

About this task
Supported configurations: If you are migrating a WebSphere Virtual Enterprise Version 6.1.1.x
or 7.0.0.x cell with middleware agents to
WebSphere Application Server, Network Deployment Version 8.5.x,
the middleware agents are not migrated. The middleware agents remain
at the previous version, and you can continue to use the middleware
agents and use the IBM® Update
Installer to install fix packs to the middleware agents separately.
However, Version 7 is the last full release of WebSphere Virtual Enterprise, and there
are no further releases of the middleware agent. To manage middleware
servers from a
WebSphere Application Server, Network Deployment Version 8.5 or later
deployment manager, it is recommended that you use the
WebSphere Application Server node agent at
the same release level. The node agent completely replaces the functions
of the middleware agent.

Procedure
- Prepare to migrate your WebSphere Application Server, Network Deployment cell. See Preparing to migrate a WebSphere Application Server,
Network Deployment cell for z/OS.
- Migrate the deployment manager to Version 8.5.
- Migrate the deployment manager node as described in Migrating deployment managers for z/OS.
- To migrate the WebSphere Virtual Enterprise artifacts
to the new WebSphere Application Server Version 8.5 cell, run the VEUpgrade command from the deployment manager node's bin directory. For example, run:
cd V85_app_server_root/DeploymentManager/bin
VEUpgrade.sh -userid adminUserID -password adminPW -sourcewashome old_app_server_root/DeploymentManager
-sourceprofilepath old_app_server_root/DeploymentManager/profiles/default
-targetprofilepath V85_app_server_root/DeploymentManager/profiles/default
- Start the deployment manager. The deployment
manager must remain started until all nodes are migrated.
- Migrate the on-demand router (ODR) nodes one at a time
to Version 8.5.
- Migrate the node as described in Migrating federated nodes for z/OS.
- To migrate the WebSphere Virtual Enterprise artifacts
to the new WebSphere Application Server Version 8.5 cell, run the VEUpgrade command from the node's bin directory. For example, run:
cd V85_app_server_root/profile_name/bin
VEUpgrade.sh -userid adminUserID -password adminPW -sourcewashome old_app_server_root/profile_name
-sourceprofilepath old_app_server_root/profile_name/profiles/default
-targetprofilepath V85_app_server_root/profile_name/profiles/default
- Migrate the remaining application server nodes one at a
time to Version 8.5 following
the same process as for the ODR nodes.
- Stop and start the new Version 8.5 cell to incorporate
your changes.
Results
Your cell is now at Version 8.5 level.
