Migrating the product

Migrating involves copying the configuration from a previous release of WebSphere® Extended Deployment into a new release.

About this task

You can perform an incremental migration of your Version 6.0.2 or Version 6.1.0.x configuration to Version 6.1.1. As a result, your system temporarily operates in a mixed cell environment in which you migrate the deployment manager to Version 6.1.1 before you migrate any nodes.
  1. You migrate the deployment manager to Version 6.1.1. The deployment manager must be at the highest release and fix level within the cell.
  2. You migrate the on demand routers (ODR) one at a time to Version 6.1.1. Each ODR must be at the same release and fix level as the deployment manager.
  3. You migrate the application server nodes one at a time.
Note: 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.
