 If users wish to upgrade their data from one OME-Zarr version to another, it migration tools will be available ([prototype here](https://github.com/scalableminds/zarrita/blob/8155761/zarrita/array_v2.py#L452-L559)).
 Migration is a fairly computationally cheap operation, because only json files are touched.

 OME-Zarr images MUST be consistent in their OME-Zarr and Zarr version.
 With this constraint, implementations only need to detect the version of a provided URL or file path once and can assume that all multiscale levels, wells, series images etc. use the same version.
