How?  You're not normally going to be running old migrations.  What 
specific problem do you think you will run into if you leave the old 
migrations around?

Can you give an example?  Are you talking about seed data, or about 
changing existing data to fit a new schema?

If the former, then you've got a great example of why you shouldn't use 
migrations for seed data.  If the latter, then there's really no issue.
