I have an early 2015 MBP with a stock 256 GB SSD running Catalina. I've been booting from an external 1 TB SSD, since I have around 700 GB of files in my Documents folder, which I sync to iCloud Drive. I just replaced the stock internal SSD with a 1 TB internal SSD from OWC and used Carbon Copy Cloner to clone the external drive to the internal drive. All went well, except that macOS thinks that all the files in my Documents folder need to be uploaded to iCloud Drive. It doesn't realize that these are the same files that are already up there. I created a couple of new documents on my MBP, but they haven't synced up to iCloud Drive and down to my iMac. How do I sync my MBP Documents files with the ones on iCloud Drive without uploading 700 GB worth of duplicates or accidentally deleting everything? Do I just log out of iCloud on my MBP and log back in?
