Hello everyone

I am in the process of upgrading old servers (hardware). Currently the
server is with debian jessie and the hosts also with debian jessie.

If I install debian stretch as a server, can I still install debian jessie
on the hosts? Or I keep on debian jessie for server.All this thinking to
future upgrade for hosts to debian stretch.

Sorry if the question is very noob.

Thank you all !

ps : sorry for my bad english :D
