How to update latest mattermlost server?

I am currently using Mattermost-Preview with Docker in a Windows environment.
Recently, a new version of Mattermost-Preview was released, and I want to update my server.
Is there a way to update to the latest version while retaining existing chat logs and data?
I would like to simply update the version and continue using it as before with my existing chat history and materials intact.

It doesn’t support upgrades as explicitly stated…? Is there a reason you’re using the preview as production which again is explicitly recommended against?

Simply because the environment our group initially set up is in preview mode.
