There may be some situations where it would be useful to reserve available disk space for future migrations. You can preallocate the disk space today and then release the disk space immediately prior to a migration in the future (or as a part of the actual migration process itself). You can reserve disk space for future migrations by creating a reserve file on the same disk volume as the system volume. A reserve file is simply a large file that takes up available disk space. In the event that you need additional available disk space in the future for migrations, you can delete the reserve file to provide additional disk space.
