Upgrade fails: Can't locate revision identified by 'e034bab4fb56'

Following the instructions from docs/01_INSTALL.md (previously README.md) for the backend:

export DO_LOCAL_CONFIG=/home/cp-server/do-portal/backend/config.cfg
source ./bin/activate
pip install -U pip setuptools
pip install -r requirements.txt
mv misc/migrations misc/tmp-migrations

python manage.py db init; all works, but: python manage.py db migrate; Fails with


(backend) cp-server@cp-backend-aec-stg:~/do-portal/backend$ python manage.py db migrate;
INFO  [alembic.runtime.migration] Context impl PostgresqlImpl.
INFO  [alembic.runtime.migration] Will assume transactional DDL.

During handling of the above exception, another exception occurred:
