Ubuntu - migrate standard installation of Plex to Docker

Hello,
using Plex server in my Ubuntu Server 18.04. Everything works great.
I just read Plex in Docker is better solution (don’t know why).

So I want to move Plex to Docker, then remove standard installation so it will be in Docker only.
And of course want to migrate stats, seen multimedia etc.

How can I do that please?

Plex in Docker isn’t a “better” solution. There are multiple, equally valid, solutions.

You should go with what you are best with; Windows, Linux, Docker, etc.

Here is the support page for moving to another system (which docker qualifies as).

Pesonally, I don’t understand the reasons for Docker:

  1. It’s abstracted from the host it’s running on
  2. It’s far less portable
  3. UID/GID/Network/media mapping can get all balled up
  4. Hardware transcoding isn’t native.
  5. It is NOT as portable as touted.

Again, personally, I think people are using Docker because they can / it looks cool.
It’s intended to be used when no native package exists.
In this case, it’s already native.
what’s the net gain?
