Sets the length of the underlying IO to be 0, without actually purging the associated data. Not supported for stores beyond `V1, which should use clear instead.

val migrate : progress:(int64 -> unit) -> t -> [ `V1 | `V2 ] -> (unit, [> `Msg of string ]) result
  • raises Invalid_arg

    if the migration path is not supported.
