Quick heads up if you use "Copy To Account" (beta function), be aware when moving lists the internal id's of the entries can change.
Creating 4 list entries in SandBox the ID's were 1,2,3,101 <-- no idea why 101 it was a brand new list nothing had ever been added to push the id range out of shape.
After moving to Prod they became 1,2,3,4 In code you should use the internal ID so watch your back!
