Transfer Calibre from iMac 27' to new Mac mini M4

[59Bob]

If I am in the wrong section someone PLEASE point me in the correct direction.
I have tried for over 7 hours to transfer Calibre from a iMac intel 27' to a new Mac mini M4.

On both devices I have Calibre 7.24 installed (Both devices are up to date)
I exported to a usb drive & moved the same to the new Mac mini & tried to import it, only to get :-

The folder /Volumes/BOBS 128 G/Calibre Exported/PDF 2 is not valid: The exported data in ._part-0001.calibre-data is not valid, version (469769983) is higher than maximum supported version.
You might need to upgrade calibre first.

Traceback (most recent call last):
File "calibre/gui2/dialogs/exim.py", line 280, in select_import_folder File "calibre/utils/exim.py", line 378, in _init_
ValueError: The exported data in ._part-0001.calibre-data is not valid, version (469769983) is higher than maximum supported version. You might need to upgrade calibre first.

I attempted various export ways to desktop & copied to new Mac, basically the same result.

In the exported folders I got for example:-
part-0001.calibre-data
part-0002.calibre-data
part-0003.calibre-data

I ran bug finder & the result:-

I am at my wits end & beyond trying to overcome this situation, so I sincerely hope someone can positively guide me in layman's language PLEASE.

Forget export/import. Just copy the libraries as is and copy the settings as is. Then copy them to the new computer.
