Let's imagine this data
```xml
<record model="my.model" id="1">
<field name="name">parent</field>
<field name="children_ids">
<record model="my.model" id="1.1">
<field name="name">child</field>
</record>
</field>
</record>
```
Loading this data the first time, everything works fine.
But if we update it, this is what happens:
* load `my.model,1`: write on `name=parent` and `children_ids=None`
* load `my.model,1.1`: write on `name=child` and `parent_id=my.model,1`
The write on `children_ids=None` can unlink all the children if the
field is declared as `ondelete=cascade`
That will leade in all the records to be deleted and recreated, but
without keeping links with other documents.
For instance, when upgrading the `account` module, all the
`account.account.tag` are removed from `account.move.line` because when
the `account.tax.report.line` are updated, all the tags are deleted and
recreated.
