How to update docker-wildduck from old version to latest?

[rqelibari]

If you use the default docker-compose.yml your mail data and configuration are already being persisted in the docker volumes mongodbs and mailconfig. To update the container you can follow the instructions on this thread and run the following commands in your docker-compose.yml directory:

$ docker-compose pull mail
$ docker-compose restart mail
$ docker image prune -f

Can you please post your configuration? E.g. the specific part of your docker-compose.yml or the docker command you run your container with.

my docker-compose.yml just like https://github.com/astzweig/docker-wildduck/blob/master/docker-compose.yml with only change

            - FQDN=mailserver1.example.com
            - MAIL_DOMAIN=example.com
           - API_URL=https://mailserver1.astzweig.de:5438

docker command just run docker-compose up -d mail

I want to use latest astzweig/docker-wildduck, but my mail server has data and settings.

how to backup these and import to new?
