Planning for migration

Before attempting to perform a migration, develop a migration plan to ensure a smooth and orderly transition. A well thought-out and documented migration plan can help minimize any interruption of service. Your migration plan should address topics such as:

• Identifying which required and optional products are needed
• Evaluating new, changed, and deleted functions
• Defining which Tivoli Workload Scheduler for z/OS functions you want to add, delete, or modify
• Defining necessary changes to:
  • The configuration
  • The initialization statements
  • Installation modifications
  • Operational procedures
  • Other related products
• Determining any restrictions during the conversion period
• Estimating the amount of time the conversion will take
• Defining education requirements for operators and end users
• Preparing your staff and users for migration.

The content and extent of a migration plan can vary significantly from installation to installation. For example, installations that have many installation-specific modifications might require extensive planning due to the added complexity.

You should also consider the following areas when defining your migration plan:

• Installation
• Initialization
• Customization
• Operation
