With Getting help of Batch Operation Docs, Create A Batch Operations on your desired content type 
On each epic load node, get your fields data,

remove old fields from the content type 


I Strongly Recommend befor write batch, try it on one node, I mean create a route ( I mean item with hook_menu) then in call back try to achieve what you want, after success convert it to a batch operation or do it with VBO + Php Filter module(instead of batch processing)
