Change single 2003 std. server internal domain suffix with exchange fro. .org to .local

Hi All,

I just picked up a client with a single domain controller 2003 standard server with Exchange and 11 workstations. I noticed the internal domain name was ABCDF.org the same as their external website domain name. The previous IT person just added an "A" record with "www" to internal DNS to allow internal domain users to view the external website .

They now want to move to SBS 2011. My goal is to possibly change the internal domain to ".local" on the existing domain prior to to the actual migration to SBS 2011.

Question:

1. Can i leave the internal domain name as is and proceed with the migration?

Thanks,

Frank

I would suggest to rename forest first before you start SBS2011 migration. For that, please check MS Exchange blog how to do that in an environemnt where Exchange 2003 is used at
http://www.msexchange.org/tutorials/domain-rename.html

Exchange 2007/2010 doesn't allow for forest/domain rename, unfortunately. DO not do that
http://www.msexchange.org/articles_tutorials/exchange-server-2010/migration-deployment/uncovering-impacts-domain-rename-exchange-server-2010-sp1.html

When you do that and everything works fine, you  may follow an article how to migrate from 2003 to 2011 at
