Updating iCloud Documents folder on long-offline MBP to match what's on current iMac

I posted this in the generic macOS forum but haven't received any responses. I have a 2015 MBP with a 256 GB SSD that I'd been booting from a 1 TB external SSD so that I could have all my files (about 700 GB) available locally. Last year, I got a 2019 iMac with a 2 TB SSD, so I no longer need to have all my files on my MBP. I disconnected the external SSD, rebooted, signed into everything that needed signing into, and updated all my apps. (Somehow, Catalina already had updated itself to the latest version.) The only problem is that my Documents folder, which is synced to iCloud, is still at the state I left left it in March 2019, the last time I'd used the MBP's internal SSD as the system drive. How do I the folder structure to update to what's on my iMac and in iCloud? Obviously, not everything is going to fit, but I currently can't access anything I created after March 2019. Equally obviously, I don't want what's in iCloud and on my iMac to be overwritten by what's currently on my MBP. Do I just unsync iCloud on my MBP and then resynch?

Never mind... I decided to go back to my 1 TB external SSD. Using my MBP's internal SSD, Office 365 told me that my account didn't allow me to write files on that device, only read (maybe it's installed on too many devices), and it kept asking me for my keychain password, which I don't know. If I decide to go back to using the internal SSD, I'll do a fresh install of macOS and everything else, but it's not worth the hassle at the moment.
