Using migrate_storage_to to shift from one NTFS drive to a bigger one formatted with large FRS /L switch so I can later enable server deduplication, per Microsoft’s recommendation for deduped volumes which may host large files.
I can find nothing called symlink_pool in my installation, or rather windows search can’t, but by “start over” do you mean for the currently migrating client (first one) or the entire installation? & do you mean restart migration, or ditch all backups & start from ground zero? I actually considered that as a migration strategy to be honest.
