Migrating a z/OS federated node: Checklist

Activities for migrating a federated node to WebSphere® Application Server Version 7.0 after you generate the appropriate Job Control Language (JCL) jobs include activities related to general preparation, transaction-log clearance, and node migration. Use the following checklist as a quick reference to these activities. Follow the instructions that were generated by the z/OS® Migration Management Tool or the zmmt command to complete the process of migrating your federated node to Version 7.0.

Before you begin

You can find more details about migrating a federated node in Preparing to migrate a WebSphere Application Server, Network Deployment cell for z/OS and Migrating a z/OS federated node.
