I'm trying to migrate a database from Odoo 14 CE to 15 CE with the help of OpenUpgrade's documentation.

During the migration process:

./odoo-bin -c ../odoo.conf --upgrade-path=/home/ODOO15/odoo/addons/openupgrade_scripts/scripts --update all --stop-after-init --load=base,web,openupgrade_framework

I am encountering the following error:

UniqueViolation: duplicate key value violates unique constraint "ir_config_parameter_key_uniq"

DETAIL: Key (key)=(mail catchall alias)  already exists.

    mail catchall alias

    catchall
