We're looking to change our domain names from ustest.com to abcustest.com.
I want to keep the old domain since all of our computers, servers is already functioning on ustest.com.
I'm thinking of setting up the email to relay the emails from abcustest.com to ustest.com.
Also I would need to reroute the traffic on from abcustest.com to ustest.com for all other functions.
We just want the website and email to reflect the new domain name abcustest.com while everything else stays the same.
Any thoughts or suggestions?
What needs to be change on our hosting side and on my side?
