I'm just building a new machine (new IP) and migrating over user data/email addresses to it
My question is:
1) I will build out the system pretty much as a clone of the old one, using test.subdomains/mx record to point to it. new "test" email addresses will be
user@test.domain.com instead of
user@domain.com
Assuming that the new system is built out properly, working, tested, etc - would all I have to do is change the zone record at registrar to point to new mail system?
that is
domain.com
mail.domain.com (mx)
xxx.xxx.xxx - A record
test.domain.com
testmail.domain.com (mx)
xxx.xxx.xxx (A record of new system)
---> domain.com
mail.domain.com (mx IP of new system)
xxx.xxx.xxx - A record of new system
Sound good?
