I read many blogs and also read microsoft documents for transition from 2003 to 2010, so lets start with my current scenario
Exchange entp. 2003 running on windows 2003 entp sp2 as 2 node cluster
out side(internet) accessing by http://mail.abc.com
mx record configured by local ISP
if we transition from 2003 to 2010
shall we have to contact our ISP for ms record ?
shall we have do any additional setting while transition for access exchange mail for out side(http://mail.abc.com) ?
if there is any setting for internet, please clarify
our plan to exchange 2010 with DAG
Thanks in advance
