I have this dilema about moving Exchange 5.5 server to a new server with a different name. I’m currently running Exchange 5.5 (~16GB data base) with SP2 no OWA. I would like to move to a different server while rebuilding this server. Should I prepare for OWA on new Server with Security(KM or Certificate server) or wait till the old server got rebuilt then implement OWA? I would like to implement security that built-in MS product (KM or Certificate server). What does it take to implement this? Iread previous post and seem there are two possible solutions( moving mailboxes and forklift) how long is each method base on my data?
