> Assumed schema was updated a number of times and there are n >1 converters to apply.
> Let's chain converters  to apply all at once rather then one-by-one having a row of intermediate version in between.
> Also, opposite changes like  "adding column A" then "remove column A" or
> "Changing column default" then "remove column A" can be effectively omitted.
