Just wanted some advice please.
Here's my current setup.....
Two main servers:
AKT01 – Domain controller (Active directory\dns\dhcp) (MS Windows 2003 Std)
AKT02 – Exchange server (MS Windows 2003 Std / Exchange 2003 server enterprise)
We now need to upgrade our current setup to MS Windows 2012 as OS and MS Exchange 2013 server
Step: 1 Migrate DC\AD to Windows 2012 to new hardware (AKT-01). This step we are able to do as we have done this in testing environment.
Step: 2 Deploy Microsoft Exchange Server 2010 in an existing Microsoft Exchange Server 2003 organization operating in native mode. Coexistence with these two Exchange.
I am comfortable with the step 1. However with step 2 I would like to progress this in hops to get to exchange 2013. For now I need to concentrate on moving 2003 to 2010. This is where I need help\assistance……
Can I carry on using both exchange (2003/2010) server and route all emails via exchange 2003 whilst I gradually move mailboxes (circa 300 mailboxes) over to exchange 2010? And then decommission 2003.
Ideally I would like to route inbound\outbound email via exchange 2003 once the mailboxes has been migrated over to 2010.
On my test environment I’ve been able to make the mail flow between two exchange servers but I need to know if I can make the exchange 2003 as routing email server out to internet even though the mailboxes resides on the 2010?
Also would it affect the OWB\OMA if it was routed out via 2003? Our SSL certificate currently is assigned to 2003 for OWA & OMA.
Your assistance is much appreciated.
