Upgrade From EV 2008 SP5 To EV 9.0 SP4 R1
I am planning to upgrade EV 8.0 SP5 to EV 9.0 SP4 R1. We are running outlook 2007 and EV client 7.5. I believe EV client 7.5 is not supported with EV 9.0 SP4 server. I am wondering which EV client I should install on the user computer which is compatible with outlook 2007. Also, if I upgrade the server first and client later would it effect message archiving? What would be in best approach for an upgrade?
