Result without migration script / Expected Result

V14 table mail_activity_type

id	name	default_description
1	Email	<p>A description</p>
2	Call
3	Meeting	<p>Another description</p>

V15 table mail_activity_type (Without migration script)

id	name	default_note
1	Email
2	Call
3	Meeting

Problem : the data is lost during them migration process, and the new column is empty.

V15 table mail_activity_type (With migration script)

id	name	default_note
1	Email	<p>A description</p>
2	Call
3	Meeting	<p>Another description</p>

Write migration Script

in the pre-migration.py script add:

from openupgradelib import openupgrade

def _rename_fields(env):
    openupgrade.rename_fields(
        env,
        [
            (
                "mail.activity.type",
                "mail_activity_type",
                "default_description",
                "default_note",
            ),
        ]
    )

@openupgrade.migrate()
def migrate(env, version):
    _rename_fields(env)
