> When performing a full migration from SegmentMK to DocumentMK, it'd be useful
> to migrate the checkpoints as well. This way we can avoid full reindexing
> which occurs after such migration. We can copy checkpoints as follows:
> 1. Get the oldest checkpoint on SegmentMK and migrate it as the DocMK head.
> 2. Checkpoint the current DocMK head.
> 3. Get the next SegmentMK checkpoint and apply the changes.
> 4. Checkpoint the current DocMK, etc.
> 5. As the last step apply the changes from the SegmentMK head.
> Since the checkpoint ids will be different, we should modify the /:async
> properties.
