Live Migrate from Backup or Snapshot
If I already have Cloud Manager backups, or can take an EBS snapshot, I want to be able to quickly Live Migrate this replica set to minimize migration time and load on my existing infrastructure.
Note that you can *restore* directly from a Cloud Manager backup to a MongoDB Atlas cluster *today*.
However, a backup restore is different from a live migrate since it will be from a point in time.
Atlas separately offers a Live Migration service which connects to your existing MongoDB environment, performs an initial sync-style data load and then applies oplog to keep the Atlas side destination cluster in sync and up to date in terms of op-time. Once the Atlas-side cluster is caught up, you can quiesce writes to your source cluster and bounce your application servers over to the Atlas cluster.
