I am using a single domain controller on Windows 2000. It is a basic DC and it works fine. Now there is a second server that also has the same server version. I am running Exchange on it. The version is 5.5. Now I am planing to go for upgrades. I am planing to go for upgrade on the DC and install all latest version of Exchange server. On the old server there are around 100 Exchange user that I am planing to migrate them. What should I do. Should I install the latest version of Exchange on existing server or simply upgrade everything by fresh installation.
