I’ve upgraded one of my Domino mail servers from 8.5.3FP3 to 9.0IFR4.
I am thinking about upgrading my mail template to 9. However I have several replicas on other 8.5.3FP3 servers and I don’t want to upgrade those servers to 9 right away. If I apply the template can I still open and use my mail files on those other servers?
