Kobo Collections advice

I've been using calibre to manage the books on my sony ereader which I am replacing with a kobo

Couldn't get the kobo to work on my PC but I have a lap top. Installed calibre there & said it was a kobo I had, copied the calibre library over via a usb stick.

I have tags in the metadata data for the books but when I transferred them over there were no collections set up on the Kobo

I'm not sure if I've missed a step :blink:

If anyone could advice I would be grateful
