9 # If the entity's ID is migrated, the Migrate API will try to update
10 # an existing entity with that ID. If no entity with that ID already
11 # exists, it will be created.
18 default_value: 'The answer is 42.'
21 # If the destination is going to update an existing user, you can optionally
22 # specify the properties that should be overwritten. For example, if the
23 # migration tries to import user 31 and user 31 already exists in the
24 # destination database, only the 'name' and 'mail' properties of the user
25 # will be overwritten. If user 31 doesn't exist, it will be created and
26 # the overwrite_properties list will be ignored.
30 # It's possible to overwrite nested properties too.
