ES5.0a1: The [string] type is removed in 5.0. You should now use either a [text] or [keyword] field instead for field

[gquintana (Gérald Q)]

Why is this automatic migration not applied when manually creating an index (in my example, monument.settings.json contains a mapping used with 2.2)? For v5. 0, it could just raise a deprecation warning.

Thanks for your explanation though
