We are thinking about migrating to Zimbra CS Network Edition from Exchange 2003. I have been reading the Admin Guide, the installation/configuration seems straight forward. My concern is with the migration from Exchange 2003. I'm having problems understanding the Migration Wizard for Exchange. Why is it that I have to create a MAPI account for the migration? It would be easier to point to the Exchange Information Store and do an import. Why do the passwords have to change? This would cause a lot of problems for our endusers.
