That’s correct. Plex.tv tracks servers by their ID. You cloned one to take to the other.  
At this point, they are mutually exclusive.

To remedy this we will change the host-native server. (don’t mess with Docker)

1. Stop Plex

2. Go to `/var/lib/plexmediaserver/Library/Application Support/Plex Media Server`

3. As ‘root’, using the text editor of your choice, edit `Preferences.xml`.

4. VERY CAREFULLY, remove the following `Name="Value"` pairs (the entire pair=value)

- MachineIdentifier
- ProcessedMachineIdentifier
- AnonymousMachineIdentifier

1. SAVE the file

2. Start PMS

3. Open the server by LAN IP and make certain it claims again.

We are going to void the certificate for this server and issue it a new one as soon as you have it running and claimed. (I need to be able to distinguish which is which at Plex.tv)

If you have other plans here - Please do let me know in advance if possible.

I didn’t know you were going to run both simultaneously.
