Plex server migration to docker based?

I have an Intel NUC running plex media server on ubuntu headless server. It's running beautifully, and barely uses the nuc's resources. The videos are stored on a synology ds923+ NAS.

I'm thinking of adding a couple of new services to the NUC and would like to move to a dockerised setup. This would involve moving the plexmediaserver into a docker.

Is there a good way to do this without having to recreate and rescan all the plex video libraries?
