We currently use zimbra 8 and are looking to move to exchange 2013 since the future of zimbra looks to be bleek. Currently we have about 20 users. I would like to get mail, calendar, contacts and notes. I have read other threads like:
Is this the best way? This procedure appears to get only mail. Is there a way to get calendar, contacts and such? I really don't want to have to export to pst and then import as this would cause hours of email downtime (zimbra server up while i export. Then configuring the router for the exchange server to accept connections then import). About half the users are connecting from the internet and therefore have to come in through the router. How do you gurus handle going from 1 email platform to another?
