Why does Migration Assistant say there's not enough space when migrating from 1TB to 2TB Mac?

I have 0.7TB used of 1TB my Mac. I am migrating to a 2TB Mac but get the error from MA that there is not enough space on target volume. Both old and new macs are running Mojave.

Not enough space for migration I just bought a new iMac and am trying migration assistant. It says there is not enough space to complete the transfer. I did a check on disk utility and everything is fine. Also checked storage and there should be plenty of space. Help!

Running Migration Assistant with insufficient space I have a 27” iMac with 3TB’s of storage. I just bought a new MacBook Air with a 1TB drive. On my iMac because of ICloud Drive, I am using 1.5 TB of storage. I have Files and Docs turned on, which puts my data in iCloud Drive, but keeps a copy on my local machine. As a result, Migration assistant consistently fails for insufficient space. On iCloud Drive, I have “Optimization” turned on, which will keep data only in the cloud if there is insufficient space. On my source machine, I have plenty of storage so the optimization is not relevant. On the target iMac ideally the optimization would solve the problem, but I have to get the migration done first. Any ideas?

Data Transfer Files not appearing I recently got a new macbook air and transferred data from my old windows PC. It seems like everything transferred but the documents folder (even though it was selected). Not sure how to transfer it because now when I try using the migration assistant it says I don't have enough space. Not sure how to delete files to free-up space either. Appreciate any help.
