You can upgrade the server to stretch, but you should make a backup
of the nfsroot used for jessie installations. You can then have two
nfsroots, one for the stretch one for the jessie installation.
A jessie installation may also run from an stretch nfsroot, but it may
cause some problems. So using the old nfsroot for your jessie
installations is the best way to do it. And then build a new stretch
nfsroot using the new FAI version for your stretch installations.


P.S.: I'm always very interested in user experiences with FAI. Can you
please fill out the FAI questionnaire
http://fai-project.org/questionnaire
and send it back to me when you finished a project with FAI.
