deeper explanation from my perspective of the solution for people who make this same mistake:
I had the cache settings for each share totally messed up. after the advice here, and space invader one's video on shares/cache pools, I set all of the problematic drives to settings that will allow the mover to move them, then disabled vm and docker, then used the mover.
after that, I will be returning games, J drive, media, and time machine backup to NO Cache
I am fairly certain this is close to correct, but if my next steps (after the. mover is done) are wrong, let me know. otherwise thanks!!!!!
