Before you migrate a WebSphere® Application Server for z/OS® Version 5.1.x or Version 6.x node to Version 7.0, you must create Job Control Language (JCL) jobs (CNTL and DATA datasets) that you run during the actual migration. You can use the z/OS Migration Management Tool to create a migration definition and upload the migration jobs.
The z/OS Migration Management Tool itself does not perform the migration; it creates batch jobs and instructions that you can use to perform the actual migration tasks. The jobs and instructions that you generate using the z/OS Migration Management Tool form a migration definition on your workstation that you then upload to your z/OS system and use for the migration.
In WebSphere Application Server Version 7.0, you can use the z/OS Migration Management Tool and the jobs as well as instructions that it generates to migrate from Version 5.1.x or Version 6.x to Version 7.0 nodes. After you actually migrate a node, however, you must use the WebSphere Application Server Version 7.0 administrative console or scripting to administer it.
