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.
- 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.
- 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.
- 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.
