I am working on an already existing site that has content.
There is a content type with field date and time. I need to remove the time component and just be Date only without deleting any content along the way. If the time data is lost, that is fine.
Can I simply delete the field and recreate it with date only? Or will that delete the existing data?
will that delete the existing data?
yep, any time you delete a field, all the data is deleted as well.
