Upgrade from 6.0.0 to 7.0.0 failed - seeing "Internal Server Error"

I’m trying to upgrade redash from 6.0.0 to 7.0.0. Upgrade was not successful and seeing - “Internal Server Error”

After following certain documents, I realized it’s require to migrate the database as well. Hence, I performed following steps

  1. Remove migrations folder under /opt/redash/redash-7.0.0/

rm -rf migrations/

  1. Drop the alembic_version table

  2. Initialise the DB, under /opt/redash/redash-7.0.0/

bin/run ./manage.py db init

  1. Upgrade the DB

bin/run ./manage.py db upgrade

  1. Migrate the DB

bin/run ./manage.py db migrate

Last 3 steps were same as my attachments

After following aforementioned steps, I could not see any new columns being added to the Database. I wonder, what could have I missed here to resolve “Internal Server Error” issue ??

Anyone knows about aforementioned issue ?
