# Update policies

All policy updates involve the creation of an update intent with the appropriate type and the `id` set to the policy to update.

Updating policies can have unexpected side effects. You need to be very careful that updates to your policies do not prevent you from creating and updating other entities in your environment.

This table lists some common policy update tasks:
