Hello, That's a large variation between the old and new cluster. Are you sure you pulled over all the SSTables for your keyspaces? Also, did you run a repair after the data move? Do you have a lot of tombstone data in the old cluster that was removed during the migration process? Are you using Opscenter?
A quick comparison of cfstats between clusters may help you analyze your situation and help you pinpoint if you are missing any data for a particular keyspace, etc as well.
