Forma how to move the configurations of Calibre to another computer?

I was using calibre in a computer for some years


I installed the app to another computer
but i needed to resinstall plugins (ok)
bur i could not handle how i had added a column in previous versions to manage my collections.

there is a "mycollections" in the left menu
and theres a record under the Kobo Utitlities /as follows

now i cant see that details in the library.

probably its not syncing this table from the kobo to the calibre


on the otherhand there is a COLLECTIONS row coming in the calibre in new computer which i can see the collection tags i had saved in previous computer.

pls advise.


reference screehshots in my previous computer Calibre:
