When you say database, do you mean the OS and the server install?

Yes, that’s what I meant. I switched my server install to a HDD because it was running on a 256 GB SSD which was running out of room.

I’m sure docker is easier if you know it… that’s like the point, afaik, but while basic use might be easy, it’s… never ever that easy for me, something always goes wrong, which is why I haven’t bothered yet. I know I should, I know it’ll make things easier (hypothetically), but it feels like a huge undertaking for someone with no skills. I’ve been looking for a super noob friendly instruction guide, and have not found one that I can work with, tbh, without a bunch of other know-how that I don’t have. (If you know of any I’d be eternally grateful!!!)

I can give you some tips for now and then I’ll give you some more in-depth instructions when I’m at my computer again.

For now:
Install Docker to your computer. I’m not sure how windows Docker handles it but I recommend using Docker compose. I’m not sure of the technical differences between Docker and Docker compose, but I found Docker compose to be much easier to use because it’s saved as a YAML file (text file). If you need to make changes, just edit the file.

Once you have that set up, get a Plex server running. You’ll probably have to change the ports in the Docker one to avoid conflict with your current one.

I recommend LinuxServer.io for a lot of things, including Plex. There’s some dissent over use of Linux Server’s apps due to permission and root things, but they are also super simple to use and you can start with the basics here.

Scroll down a bit to find the docker-compose section. To start a sample plex server, make the following changes:

Remove network_mode: host

In line with environment and volumes, add this:
ports - 324001:32400

This will route 32400 of the docker container to 32401 of the host network, allowing you to have both servers running at the same time without a port conflict.

Edit the volumes as needed. Always remember, it goes: host: container for everything. You can change it however you need. /config should preferably be on an SSD, as I said. The rest can be created as needed. For mine, I have both movies and TV shows stored under a folder called /media/. My plex docker script mounts /media/ and in plex I can search through the subdirectories to find the TV and Movies section.

Your second (temporary) plex server should be set up properly once you start the container

I’ll tell you how to data over to the Docker container later.
