I am currently attempting to migrate from SBS2003 to Server 2012 R2 Hyper-V host with several Server 2012 R2 VMs and Exchange 2013. I understand that there is no direct migration of Exchange 2003 to 2013. I have setup a VM running Server 2008 and installed Exchange 2010.
I have been reading a bunch of guides on this process and have become confused about the appropriate setup of DNS.
The current setup is this: we have a website hosted by a third party; let's say www.company.org
. All external incoming email (sent to anyone
@comany.org) goes to the web-host and is then redirected immediately to our Head Office external IP address.
The public address of our current server (i.e. the SBS2003 box) is: local.company.org
So, this is used for Remote Desktop Connections, OWA, etc.
It seems that to get Exchange 2010 working, I need to change my DNS settings to something like this:
local.company.org > 192.168.0.100 - IP address of SBS 2003 box (including Exchange 2003)
legacy.company.org > 192.168.0.100 - IP address of SBS 2003 box (including Exchange 2003)
local.company.org > 192.168.0.223 - IP address of Exchange 2010
autodiscover.company.org > 192.168.0.223 - IP address of Exchange 2010
We have an SSL123 certificate for local.company.org and it is installed on the SBS box.
I was following this guide:
and I am supposed to configure a new Forward Lookup Zone for company.org, with the above settings. Obviously as soon as I did this I could no longer get to www.company.org
So, I am not sure how I get out of this.
I am told that I should have a UC/SAN certificate for Exchange 2010 that I can then reuse for Exchange 2013 when I migrate over to there.
Can I configure DNS so that only www.company.org
goes to the web-host and everything else comes here?
