I've actually used the vol and aggr rename commands frequently, not in the process of migration. My current environment was\has been in disarray before my arrival and I'm trying to go back and standardize and clean up some things.
That said, in the pretext of migration, perhaps it should be an optional thing to rename the exports/shares?

You can stop ONTAP from automatically editing /etc/exports with
options nfs.export.auto-update off
Then whenever you create, delete, or rename a volume you get a warning that /etc/exports needs to be edited, but ONTAP leaves it alone.
I would "exportfs -u" the old stuff before renaming anything. Then after renaming the volumes so that the new volume has the old name, I would "exportfs -a" to export the new stuff.
As for CIFS, I am pretty sure that you need to delete your old shares before renaming the volumes, rename, and then create the shares again.
