Hi folks I'm looking at upgrading the email infrastructure as our current mail system is a bit old and getting full. So, what I plan to do is to have a clustered Exchange 2010 environment and drop the old mail environment which is a mailserver and a frontend mailserver for OWA. I am wondering if I am going about this the right way, and also have a few questions. Hopefully someone can help :) My rough plan: Build 2 new Windows 2008/Exchange 2010 servers, put them in the domain etc. Move a mailbox to test it. Setup clustering Move rest of mailboxes Point the external OWA to the new Exchange 2010 server. Obviously there will be testing inbetween steps etc, but am I going about this right way? Also, for OWA in Exchange 2003 you need a frontend server but you dont need that in Exchange 2010 right? Can you move mailboxes from an Exchange 2003 server to Exchange 2010 through the AD mmc console? Thanks!

Hello In Exchange 2010 there is new feature DAG ( Data Availibility Group) which is the replacement if SCR SCC CCR LCR technology. So you can go with exchange 2010 DAG for Migration from Exchange 2003. Also you can Make Exchange 2010 as a Front end server for access Legacy Exchange Mailboxes. For Migrating Mailboxes you need to use EMC (Exchange Management Console) There is a step by step method for Migrating Exchange 2003 to 2010 you can follow this below links http://www.simple-talk.com/sysadmin/exchange/upgrade-exchange-2003-to-exchange-2010/ http://technet.microsoft.com/en-us/library/aa998186.aspx http://www.howexchangeworks.com/2009/08/mailbox-move-in-exchange-2010.html Thanks Mhussain Thanks Mhussain
