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.
