Transfer old my mirror 6tb to new my cloud home duo 8tb

I’ve just bought a my cloud home duo 8tb to replace my 6tb my cloud mirror

Can anyone tell me the fastest was of transferring from the my cloud mirror to the my cloud home duo?

Also is there a way to backup my plex data so I can transfer that too without having to start over?

Thanks for the help

The best and fastest I’ve found is google old “drag and drop” and that a NO on the Plex.

Really? You cant backup the plex database?

My Cloud Home is Android OS and shell access is not exposed so there’s no way for a normal user to access the Plex database and configuration files. It can be done on My Cloud because you’ll have full SSH access. Unless someone has a better way via Plex App
