How to move sets and what should I do with cracked arms?

Hello all! I'm moving in the next week or so and I have some awkward sets I need to move.

Tantive IV 75244

20th anniversary Slave I 75243

Darth Vader's Castle 75251

Yoda 75255

Also, unfortunately my Captain Antilles and Rebel Fleet trooper have cracks in there arms, I have no idea what cause it ( I think it's the weak morals of the rebellion) but I really enjoy these figures. I don't plan on selling but it irritates me that it cracked, do you guys replace cracked arms or leave them?

Thanks all!
