Problem with back up - from Mac mini to linux

Gentlemen - for the past two years I used Roon on a mac mini - yesterday I bought a SUPERKOMPUTER - which is rooncore, based on LINUX. I made back up on mac mini - I transferred it to NAS server. Unfortunately - despite many attempts I am not able to recreate my settings from the last back up. Is that so, with roon core on linux - does not read back up with roon core mac mini? What am I doing wrong?

Perhaps you can detail how you made the backup and then the restore…there are details in the KB on how to move core from one machine to another.
