ArcGIS Pro Import Metadata with ArcPy

It is discussed in the documentation here: https://pro.arcgis.com/en/pro-app/arcpy/metadata/migrating-from-arcmap-to-arcgis-pro.htm

I just use a simple wrapper:

import arcpy
from arcpy import metadata as md

def pro_import_metadata(source_metadata:str, import_type:str, target_metadata:str, enable_automatic_updates:bool):  
    target_item_md = md.Metadata(target_metadata)
    target_item_md.importMetadata(source_metadata,import_type)

    if enable_automatic_updates:
        target_item_md.metadata_sync_option = 'ALWAYS'
        target_item_md.reload()
    target_item_md.save()

Do note that the Import_Type strings has changed from Desktop.
