 ### Migration with downtime 
 
-The managed migration approach involves the customer partnering with Microsoft to bulk-migrate all the PTU commitments in a subscription/region at the same time. It works like this:
-
-1. The customer will engage their account team and request a managed migration. A migration owner from the Microsoft team will be assigned to assist the customer with migration.
-2. A date will be selected when all resources within each of the customers' subscriptions and regions containing current PTU commitments will be migrated from committed to hourly/reservation billing model. Multiple subscriptions and regions can be migrated on the same date.
-3. On the agreed-upon date:
-    * The customer will purchase regional reservations to cover the committed PTUs that will be converted and pass the reservation information to their Microsoft migration contact.
-    * Within 2-3 business days, all commitments will be proactively canceled and deployments previously under commitments will begin using the hourly/reservation payment model.
-    * In the billing period after the one with the reservation purchase, the customer will receive a credit for the reservation purchase covering the portions of the commitments that were canceled, starting from the time of the reservation purchase.
