# Document your migration principles
<a name="document"></a>

After reviewing the landing zone and on-premises considerations, you should document your answers and decisions. These become the migration principles that guide the rest of the project.

Do the following:

1. In the [foundation playbook templates](samples/foundation-playbook-templates.zip), open the *Migration principles template* (Microsoft Word format).

1. Review the infrastructure, operations, and security considerations in the [Landing zone considerations for a large migration](landing-zone.md) and [On-premises considerations for a large migration](on-premises.md) sections of this guide, and discuss the questions with the recommended teams.

1. Document the infrastructure, operations, and security decisions in your migration principles document. For examples of how to record these decisions, see the following table.

1. As needed for your use case, add new categories, items, and principles. For example, you might want to record migration principles for portfolio assessment or project management decisions.

The following is an example of how you might record your decisions to some of the questions in this guide.
