I haven't worked with 2008 yet, but I assume that there are AD changes made when you install your first 2008 DC.
That means that apart from Exchange considerations, you'll be in trouble if you remove your only 2008 DC. ________________________________ From: James Kerr [mailto:[email protected]] Sent: Friday, August 21, 2009 10:34 AM To: MS-Exchange Admin Issues Subject: Re: demoting DC with Exchange 07 That sounds about right. ;-) ----- Original Message ----- From: Kennedy, Jim<mailto:[email protected]> To: MS-Exchange Admin Issues<mailto:[email protected]> Sent: Friday, August 21, 2009 1:17 PM Subject: RE: demoting DC with Exchange 07 Good news is now you can do all of this during regular hours. Bring up the new mailbox server....then set the mailbox moves for 3 AM it can all be automatic......nice and smooth...after all the mailboxes are moved wait a couple of days. Outlook will find the new server for your users if the old server is there. When they have all done that you can uninstall it then DCPROMO Enjoy the weekend! :) From: James Kerr [mailto:[email protected]] Sent: Friday, August 21, 2009 1:15 PM To: MS-Exchange Admin Issues Subject: Re: demoting DC with Exchange 07 Well, I guess I will be off this weekend then. I have another server coming in soon. I guess I will migrate over to that when it comes in and run Exchange by itself and then setup the old one to be a DC. ----- Original Message ----- From: Kennedy, Jim<mailto:[email protected]> To: MS-Exchange Admin Issues<mailto:[email protected]> Sent: Friday, August 21, 2009 1:04 PM Subject: RE: demoting DC with Exchange 07 After some more googling and looking it appears that you will be able to run DCPROMO and it will remove the DC. But then all hell is going to break loose in your Exchange system. CAS is going to be broken along with OWA authentication. Sorry man, but you really need to migrate the exchange off that box first. From: Kennedy, Jim [mailto:[email protected]] Sent: Friday, August 21, 2009 1:01 PM To: MS-Exchange Admin Issues Subject: RE: demoting DC with Exchange 07 I am not sure you are even going to be able to run DCPROMO, though I have never tried it. I think you may have to migrate Exchange off of it first. Installing Exchange 2007 on Directory Servers For security and performance reasons, we recommend that you install Exchange 2007 only on member servers, and not on Active Directory directory servers. Although installing Exchange 2007 on a directory server is supported, it is strongly discouraged. However, you cannot run DCPromo on a computer running Exchange 2007. After Exchange 2007 is installed, changing its role from a member server to a directory server, or vice versa, is not supported. http://technet.microsoft.com/en-us/library/aa996719.aspx -----Original Message----- From: James Kerr [mailto:[email protected]] Sent: Friday, August 21, 2009 11:49 AM To: MS-Exchange Admin Issues Subject: demoting DC with Exchange 07 I need to demote a 08 server DC that is also running exchange 07 this weekend. Any gotchas I need to worry about or should just be a standard demotion event? The other DCs are all 03 servers, don't think that complicates anything. Thanks, James
