Ok....i made some changes to the settings by changing the custom rsync flags from -X to -avPRX.
I am now able to uncheck the 'dry run' but when I do a Plan...i get multiple errors (wasn't able to get a screenshot). I was able to click on Move and it performed successfully.
I did end up changing the custom rsync flags to 'default' and still able to uncheck 'dry run' and currently moving 5.7 GB of images from one disk to another.
Trurl, thank you for the assist. It's much appreciated!
BTW, finished moving 383 GBs of data in 2h25m! Unbalance worked PERFECTLY!
