-  MigrationType.apply: CohortSpec -> MigrationType
-  was introduced to help remove the `if else if else if ... else` pattern that was showing up as we started to
-  have more migrations, notably the SupporterPlus 2023 migration after the membership annuals. Having defined a
-  sealed trait means that we can use a `match / case` layout, which makes the code more readable
-
-  MigrationType does not identity a migration (despite the fact that some migrations map to a unique migration type)
-  It simply helps identify common code used by possibly more than one migration. For instance all the pre 2023 migrations
-  map to `Legacy`
