I am preparing to switch our email over to zimbra, and have set the date to switch.
My question is, can I do the install ahead of time without dns being changed , so as not to affect the current email system, obviously the install script will not find the correct mx record (probably will even unplug network cable), but is the message I will get safe to ignore, and will the install complete ok.
Or is there a better way to pre load the server to make the switch?
Thanks in advance.
BTW This is a great product I considered putting the pieces together myself until I found Zimbra, the install is painless and I get all I was looking for and more. Absolutely great product I will not hesitate to recommend Zimbra to all my clients.
