unRAID - Move from Plugin to Docker

Hi
Am looking to move my PMS install from an unRAID plugin to a docker install.
All media will remain in same location.

I want to install a new docker version but then keep all my settings, meta, covers etc.

My current version has files going back 9+ years so i want to cut all the old rubbish.

Can anyone help with some instructions?

Am ok with how to install docker and map media shares but how do i then keep all my settings etc?

Thanks
