iCloud Drive need to finish updating before continuing with sign out, spinning wheel for last 8 hours.

I'm cleaning my Mac Book Air (Mid 2012) to factory settings to give to my granddaughter. I purchased a new Mac Book Air M1 Chip, transferred all my files and then continued to use my old MBA just to make sure all my files transferred. I started updating iCloud drive before wiping the drive and reinstalling macOS. I started the update last night, this morning the window shows "Downloading 3 items )14.20 GB of 16.32 GB)". That is what it showed this morning and what it still shows, over 11hours. How long should this take? Only 2.12 GB remaining to download. The wheels are spinning, but not going any where! Should I click "Cancel" and start over or click "Stop Updating and Continue"?
