    I still have some old nodes on CentOS 6 with perfsonar 4.0.
    
    If I follow the upgrade procedure at 
    https://docs.perfsonar.net/install_migrate_centos7.html, is this likely 
    to work when jumping straight from 4.0 to 4.2 ?

That should be no problem.  pScheduler can self-upgrade from the earliest 
release and pSConfig should take over your old MeshConfig setup.
    
    (I realise that I'll lose the bwctl backward compatibility - so nodes 
    upgraded to 4.2 won't be able to talk to remaining 4.0 nodes in the 
    interim. I can cope with that)

Anything 4.0 and later runs pScheduler, so all you will lose in 4.2 is the 
ability to talk to 3.x systems.  We stopped installing BWCTL by default in 
4.1.  Just make sure any ACLs you have ahead of your old nodes are configured 
per our guidelines and you shouldn't notice the difference.
