we are changing our domain name along with the migration.
we are using 2 (old and new) domain names for a 2 month transition
users name is john hugh
old domain firstname.lastname@example.org (the set up for our users is last name first email@example.com
new domain firstname.lastname@example.org (we are going to first name (dot) last email@example.com
is there an easy way to do this or am i going to have to type in a smtp address for every user.
should i do this on the old box before i migrate to the 2010 box?
