Performing premigration tasks
About this task
This migration procedure is for a single deployment environment. A deployment environment is a logical grouping of clusters that work together as a unit, so a deployment environment might consist of an application cluster and a messaging cluster, or might consist of an application cluster, a messaging cluster, and a support cluster. On z/OS, a deployment environment typically groups the application, messaging, and support infrastructures into a single cluster. If you have more than one application cluster, you have multiple deployment environments.
If you have multiple deployment environments in your source version, you must repeat the migration procedure for each deployment environment that you want to migrate. Use the migration properties file that is used as input for most of the migration commands to specify the source and target deployment environment configurations.
