Added a server 2008 that is taking over everything the SBS2003 used to do including Exchange. I want to be able to remove the SBS2003 Server completely (needs to be re-rolled).
What do I need to consider to get the Exchange mail traffic flowing correctly over to the new server BESIDES:
pointing the all the firewall SERVER portforward to the new server IP for everything including SMTP, IMAP etc
Can I just demote the OLD server and remove it or is the new installed exchange going to start crying because the SBS2003 Exchange Server is gone?
I have not configured anything specific in regards to how both servers play together. All I've done is:
1. Install the Server 2008
2. DCPROMO it in the domain and add it as a DC
3. Install Exchange 2010
4. Use the Exchange 2010 tools to move a mailbox from the SBS2003 Exchange Server (This of course renders the mailbox moved over and it's user useless. Can no longer check OWA that mailbox etc).
What steps do I need to make sure to do before just directing the firewalls email traffic t the new server? Wanna test this tonight after business hours...
