Task 3: Performing wave planning and metadata collection

This is the final task for portfolio assessment and wave planning. In this task, you use the application information and target migration pattern to build move groups, assign move groups to waves, and collect all the metadata needed to support the migration. Finally, you notify the migration workstream that the wave is ready.

You need the following information to complete this task.

Input	Source
A list of prioritized applications	Created earlier in the implementation stage, in Task 1: Prioritizing the applications
Migration pattern mapping	Created earlier in the implementation stage, in Task 2: Performing the application deep dive
Application target state (if applicable)	Also created in Task 2: Performing the application deep dive

Do the following:

1. Follow the instructions in your wave planning runbook, in the Stage 2: Perform wave planning section. You defined this process in this playbook, in Step 3: Finalize the wave planning process.

2. Follow the instructions in your metadata management runbook, in the Stage 2: Collect metadata section. You defined this process in this playbook, in Step 3: Document metadata requirements and collection processes in a runbook.

3. Notify the migration workstream that the wave plan is complete and that the metadata is ready. This communication should adhere to the governance you defined per the Project governance playbook for AWS large migrations.

At the end of this task, you have completed the following.

Output	Description
Wave plan	You have planned a wave, identified the servers, applications, and databases in that wave, and defined a start date and cutover date and time.
Source infrastructure metadata	You have collected the source infrastructure metadata, such as the server names and operating systems.
Target infrastructure metadata	You have collected the target infrastructure metadata, such as the target subnets, security groups, and AWS account.
Notification completed	You have notified the migration workstream that the wave plan and metadata are ready.

The portfolio team repeats all three tasks in this stage for each sprint until the migration project is completed.
