Wanted change

I've been migrating an existing calibre-web container that i've used for years and needed to change the port to reduce conflicts with other services already running on the same host. Is it possible to do this without a fresh install of the entire application?

If i need to remove certain ephemeral files, would anyone know which ones? like blowing away the calibre-web config volume?

Reason for change

reduce the need for a clean install of an existing deployment and wiping out its database and other related info.
