It depends how do you add the new field --

1. Are you using some existing FILLER from the copybook?
2. New field will be referenced in other programs or not?
3. Have you added a brand new field, which affects the length of copybook?

From above, which option/s would you choose for? Answers would vary according to your choice/s.

OPtion 3

Good, now you know what you want to do...so what consequences can you think of for that change?
