Is there a feature to update the value of an existing locale?
For instance, changing a locale on Prismic from "en-ca" to "en" without having to delete and recreate one?
I have already like 200+ existing pages on that locale, I'd like to avoid having to recreate a new locale and perform a migration on it :/
There isn’t an automated way to update the value of an existing locale. To achieve this, you would need to add a new locale and use the Migration API to transfer your content to the new locale. Once the migration is complete, you can delete the old locale.
