Issue with downgrade from 3.0.0 to 2.10.3

[sowmyachitti]

Initially used pip install apache-airflow and then later realized our dag is incompatible with 3.0.0 so then used pip install apache-airflow ==2.10.3 and does airflow db downgrade —to-version 2.10.3 -y

The dag code was compatible till 2.10.3 version Now when I try to reinstall the 2.10.3 I get below error

``Unable to import at 0027_2_10_3_fix_dag_schedule_dataset_alias_reference_naming.py

ImportError: cannot import name ‘mysql_drop_foreignkey_if_exits’ from ‘airflow.migration.utils’
``

initial diagnosis : observed that utils.py have that function in 3.0.0 but when I downgrade it still searches for that function which don’t exists in utils.py

I have a similar issue too. Version 2.10.5, made a small change to my DAG only on April, 24th and pushed it. Getting the same error: ImportError: cannot import name ‘mysql_drop_foreignkey_if_exits’ from ‘airflow.migration.utils’. Is this because of some updates were made in early April to 2.10 to easy migrate to 3.0? Any ideas how to fix import name ‘mysql_drop_foreignkey_if_exits’ from ‘airflow.migration.utils’?
