I’m just building a newer, faster plex server and wondered if there was a way I could tell the new server about the existing optimized files I have stored in my media file structure. Seems ridiculous to have to create them all again when they are there in a structure that a plex server created. However, I cannot seem to find a way to achieve this?
If you can manage that all the media files are accessible on the new server like they were on the old one
(i.e. same drive letters / folder names and paths) then you can transfer the old server installation as-is and all existing optimized versions and all metadata are valid and will be available.
If done right, PMS won’t notice it runs on different hardware.

No, you cannot reuse optimized files. But you can use them as just another version.
Its interesting about moving the server, however, I’m moving from a mac to windows 10 (even though its the fastest machine in the house no one here can work out how to use windows 10 so its become spare). I have been able to move the server in the past between macs using time machine as well which is really easy to do.
