Result without migration script / Expected Result

V14 table `calendar_contacts`

id	user_id	partner_id	active
1	1	34	true
1	2	52	true
1	3	22	false

V15 table `calendar_filters` (Without migration script)

id	user_id	partner_id	active	partner_checked
[empty table]

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

V15 table `calendar_filters` (With migration script)

id	user_id	partner_id	active	partner_checked
1	1	34	true	true
1	2	52	true	true
1	3	22	false	true

Contribution to OpenUpgrade

apriori.py file

The list of the renamed models is present in a apriori.py file in each version of openupgrade.

Until version 13, the file is present in this path: odoo/addons/openupgrade_records/lib/apriori.py.
from version 14.0 onwards, the file is present in this path: openupgrade_scripts/apriori.py.

Add a key in the following dict:

renamed_models = {
    "calendar.contacts": "calendar.filters",
}

See Full v15 apriori file.

Note:

This code is NOT used by openupgrade itself, during the migration process. It is used to generate correctly the analysis files, during the initialization of the Openupgrade project, for each release.

Write migration Script

in the pre-migration.py script add:

from openupgradelib import openupgrade

@openupgrade.migrate()
def migrate(env, version):
    openupgrade.rename_models(env.cr, [("calendar.contacts", "calendar.filters")])
    openupgrade.rename_tables(env.cr, [("calendar_contacts", "calendar_filters")])

See Full pre migration Script.
