This scenario covers migrating cells on the same host. If you intend to migrate cells to a different host, see Migrating cell configurations to new host machines using the command-line tool.

About this task

You can use the command-line tools to migrate a cell from a previous version of WebSphere Application Server to Version 8.5. The cell configuration consists of a deployment manager with one or more nodes, a web server, and an application client. All ports are migrated forward into the new configuration. This procedure assumes that the previous configuration is running. For more information, see the information about the clientUpgrade command.

Avoid trouble Avoid trouble: Ensure that your setting for the maximum number of open files is 10000 or greater. If the number of open files is too low, this can cause various migration failures.gotcha
