I am running a synology ds418 with 12TB on 4drives set up as plex server.
How can i copy all to new synology ds423+ with 40TB on 4drives?
Easy or Not?
Have found after setting up system i need File transcoding.
any help appreciated.

Yes, you could link them both together like this https://nascompares.com/map-network-drive-in-synology/
And then copy.
