# Upgrading Connectware to 1.7.0 (Docker)

How to upgrade Connectware to version 1.7.0 on Docker.

Connectware 1.7.0 affects the backward compatibility of the Connectware broker. Older broker data volumes are not compatible with brokers of Connectware 1.7.0 and newer. Upgrading to Connectware 1.7.0 requires additional upgrade procedures.

Additionally, multi-factor authentication (MFA) is now controlled via a dedicated configuration switch.

## Check your upgrade path

This upgrade is one step of a longer upgrade path. Before you continue, check [Connectware Upgrade Paths](/2-6-1/deployment/upgrading-connectware/upgrade-paths.md) to determine which steps apply to your installation.
{% endhint %}

## Important Notes

This upgrade will delete all persisted data of the Connectware broker. This includes client sessions, subscriptions, and retained data. If your configuration relies on any type of data persisted by the broker, make sure to properly initialize your applications after the upgrade.

If you rely on persisted data, create a backup or snapshot of the broker data volumes. This allows you to roll back in case of complications.

## Upgrading Procedure

1. To stop Connectware, go to the Connectware installation directory (default: `/opt/connectware`) and run `docker compose down`.
2. Delete the broker data volume of Connectware. Find the broker data volume in the list of volumes with `docker volume ls` and delete it with `docker volume rm <connectware_brokerData>`.
3. If you are using multi-factor authentication (MFA), set the environment variable `CYBUS_MFA_ENABLED` to `true` inside your .env file.
4. Download and install the new Connectware version. For more information, see [Upgrading Connectware (Docker)](/2-6-1/deployment/upgrading-connectware/on-docker.md).

## Querying This Documentation
If you need additional information that is not directly available in this page, you can query the documentation by asking a question.

Perform an HTTP GET request on the following URL with the `ask` and `goal` query parameters:

```
GET https://docs.cybus.io/2-6-1/deployment/upgrading-connectware/on-docker/to-1-7-0-on-docker.md?ask=<question>&goal=<user_goal>
```

`ask` is the immediate question: it should be specific, self-contained, and written in natural language.
`goal` is what the user is ultimately trying to achieve, the reason they need the answer. Sharing it helps GitBook give you a better, more relevant answer. A goal is most helpful when it describes the outcome the user wants rather than restating the question. For example, with `ask=how do I create an API token`, a goal like `automate deployments from our CI pipeline` lets GitBook tailor the answer to that use case.

The response will contain a direct answer to the question and relevant excerpts and sources from the documentation.

Use this mechanism when the answer is not explicitly present in the current page, you need clarification or additional context, or you want to retrieve related documentation sections.
