I believe it should look for new domain default management class 


Besides , you should also consider increasing backup retention associated to 
policy domain. If any object bound to specific management class and if it 
doesn't found the same management class in your new domain then it will 
consider policy domain backup retention grace period. 

So it would also protect your data
