##### How to fix the "listening to port 5005" issue
Fix for this issue have been published to the acryldata/datahub-upgrade:head tag. Please pull latest master and rerun
the upgrade script.
However, we have seen cases where the problematic docker image is cached and docker does not pull the latest version. If
the script fails with the same error after pulling latest master, please run the following command to clear the docker
image cache.
```
docker images -a | grep acryldata/datahub-upgrade | awk '{print $3}' | xargs docker rmi -f
```
#### Helm Deployments

running the above docker image to migrate to the new stores.

#### Docker Compose Deployments
The easiest option is to execute the `run_upgrade.sh` script located under `docker/datahub-upgrade/nocode`.
```
cd docker/datahub-upgrade/nocode
./upgrade.sh
```
In both cases, the default environment variables will be used (`docker/datahub-upgrade/env/docker.env`). These assume
that your deployment is local. If this is not the case, you'll need to define your own environment variables to tell the
upgrade system where your DataHub containers reside.
You can either
1. Change `docker/datahub-upgrade/env/docker.env` in place and then run one of the above commands OR
2. Define a new ".env" file containing your variables and
execute `docker pull acryldata/datahub-upgrade && docker run acryldata/datahub-upgrade:latest -u NoCodeDataMigration`
