Migrating from WebSphere Virtual Enterprise

Migrating involves copying the configuration from a previous release of WebSphere® Virtual Enterprise into WebSphere Application Server Network Deployment Version 8.5.

About this task

You can perform an incremental migration of your WebSphere Virtual Enterprise Version 6.1.1.x or Version 7.0 configuration to WebSphere Application Server Network Deployment Version 8.5. As a result, your system temporarily operates in a mixed cell environment in which you migrate the deployment manager to WebSphere Application Server Network Deployment Version 8.5 before you migrate any nodes.
Best practice: Even though the method of incremental migration creates a mixed cell environment, avoid running the mixed cells for an extended period of time. You should have an existing plan in place to migrate your entire cell to the highest level to ensure consistent administration of the nodes.

Procedure

  1. Migrate the deployment manager to WebSphere Application Server Network Deployment Version 8.5.

    The deployment manager must be at the highest release and fix level within the cell.

  2. Migrate the on demand routers (ODR) one at a time to WebSphere Application Server Network Deployment Version 8.5.

    Each ODR must be at the same release and fix level as the deployment manager.

  3. Migrate the application server nodes one at a time.
