having run `docker run --name mattermost-dev -d --publish 8065:80 mattermost/platform` on mattermost ver 1.1  
we would like to test version 1.2 but we would like to keep all the authorisations and all we made in the current running instance.  
Is there a way we can do that?  
Thank you!

It’s stated as a “single container preview” - so the team is stating this was meant to be ephemeral.

Two paths (the team might know yet another way):

### 1. You can extract your data and then use a newer version, with a more permanent setup

You can get a working shell inside the running container with `docker exec`, you can find mysql credentials [here](https://github.com/mattermost/platform/blob/master/docker/1.1/Dockerfile) and probably do a mysql dump.

To copy files out of the container and to your host, you can use `docker cp`.

### 2. You can try and upgrade the instance inside the container

Again, use `docker exec` to gain a shell inside the running container, then upgrade the Mattermost instance from inside the container.

Hi @mihai_satmarean,

Thanks @pearofducks for the response. Have you taken a look at our [Upgrade Guide](https://github.com/mattermost/platform/blob/master/doc/install/Upgrade-Guide.md) as well?
