I've suddenly realised that it is almost certainly not that problem at all.  
The problem, I think, is that /etc/exports still has the nfs(3) exports.  I 
understand that I could remove them using the -F and -U  flags with chgnfsexp, 
but that would make them unavailable to my older systems.

I think it means that I have to concentrate on getting the older systems using 
nfs4 as well, after which I can remove the old exports.
