Took the plunge to Big Sur last night and the upgrade seemed to go well. No delays or hangs as reported by some.

However, I do have one big problem: All of my Address Book and Calendar entries have been duplicated.

Obviously, this relates to iCloud, but I'm not sure of the fix. All help appreciated. Thanks.

Edit: Actually, this is only affecting my Address Book. The duplicates I saw in Calendar were all birthdays being generated twice because of the duplicate entries in Address Book.

Any ideas on resetting Address Book? Thanks.

In Contacts go to the top menu and find "Card, then "Look for Duplicates". It will give you the ability to merge all the duplicates.

Thanks. I had tried that and, oddly, it only returned three duplicates, even though ~400 entries had been duplicated exactly.

I solved this by logging in at iCloud.com, where I discovered the Big Sur update had uploaded a vCard into Contacts with an exact copy of my Contacts. Deleting that eliminated all of the dupes.
