We're revisiting Migration Step Twenty Eight
This has always been a confusing step to me as it says "Here do these steps". What it should say is "Yo, go back and double check that you've done step 1, 2, 3, 4, 5, do steps 6 through 10.
Prepare your organization for removal of the last server running Exchange Server 2003
Tasks to complete prior to uninstalling Exchange Server 2003
1. Move all mailboxes.
2. Move all contents from the public folders.
3. Move the Offline Address Book Generation Process.
4. Remove the public folder mailbox and stores.
5. Verify that you can send and receive e-mail to and from the Internet.
6. Delete the routing group connectors.
7. Delete or reconfigure the Mailbox Manager policies.
8. Move the public folder hierarchy to the Exchange 2007 Administrative Group.
9. Delete the domain Recipient Update Services.
10. Delete the Enterprise Recipient Update Service.
For detailed instructions about how to complete these steps, see the section “To remove the last Exchange 2003 or Exchange 2000 server from an Exchange 2007 organization” in the article "How to Remove the Last Legacy Exchange Server from an Organization" at the Microsoft Web site (http://go.microsoft.com/fwlink/?LinkId=141927 ).
We have moved mailboxes. Check. We know this because our mailboxes say "User Mailbox" not "Legacy Mailbox" when you go into Exchange Management console, then Recipient configuration, then click on mailbox.
We have moved public folders. I know this because the SBS 2003 box is off, and I've gone into Toolbox, then into Public Folder Management console and my default public folders are there. I also fired up OWA on the box, logged into a mailbox, clicked on Public folders to confirm that the info is there.
We have moved the offline address book.
We have moved the public folders. See above.
We can send email. We've checked this.
We now need to delete the SBS 2003 <<>> SBS 2008 connector that bridges across.
We need to delete or reconfigure the mailbox policies For this I'll turn the SBS 2003 back on.
We will move the public folder hierarchy to the 2007 hiearchism.
We will MOVE (not delete) the Recipient update policies. We can delete if we so deem, but moving was easier than pulling out ADSIedit for sure.
So for the steps we have left, first up is to log back into the turned off SBS 2003 and to move the public folder hierachism.
We have to go back to the 2003 box because that's where our GUI is. If we did these steps on the SBS 2008 we'd be breaking out the Powershell. There's a nice overview of what was depreciated in Exchange 2007 from 2003. Obviously someone on the Exchange team has a thing for Powershell and a thing against GUI. You might also want to learn how to use this as well.
So we need to remove the connectors. As this article says you can do it via PowerShell/Exchange command shell or GUI. And as Philip showcases, just find the connectors and delete them out. It will say "are you sure" and it doesn't matter which one you delete first.
So next we will move the public folder hierachy to the 2007 box.
On your Exchange 2003 or Exchange 2000 server, perform the following steps to move the public folder hierarchy from the Exchange 2003 or Exchange 2000 administrative group to the Exchange 2007 administrative group:
- In Exchange System Manager, expand Administrative Groups, right-click Exchange Administrative Group (FYDIBOHF23SPDLT), select New, and then select Public Folders Container.
- Expand the Exchange 2003 or Exchange 2000 administrative group that contains the public folder tree, expand Folders, and then drag Public Folders to Folders under the Exchange 2007 administrative group.
- Find them in the old server, copy/drag them over to the 2007 server
Deleting the receipient update services
- Perform the following steps to delete the domain Recipient Update Services:
- In Exchange 2003 or Exchange 2000 System Manager, expand Recipients, and then select Recipient Update Services.
- Right-click each domain Recipient Update Service, and then select Delete.
- Click Yes.
I want to remove this one as Michael B. Smith Exchange guru said "If you point it to the new box, then you still can create new users using the old tools, but their Exchange attributes will be fubar'ed. Not a good thing" Last night I browsed to the new box, tonight I'm changing my mind (like a female only should).
You will not be able to delete the Recipient Update Service (Enterprise Configuration) by using Exchange 2003 or Exchange 2000 System Manager. Perform the following steps to delete the Recipient Update Service (Enterprise Configuration) by using ADSI Edit (AdsiEdit.msc):
- Open ADSI Edit, expand Configuration, expand CN=Configuration,CN=<domain>, expand CN=Services, expand CN=Microsoft Exchange, expand CN=<Exchange organization name>, expand CN=Address Lists Container, and then select CN=Recipient Update Services.
- In the result pane, right-click Recipient Update Service (Enterprise Configuration), click Delete, and then click Yes to confirm the deletion.
On this one I can either delete or point it to the new box. (Pointing it to the new box was easier and if need be I can always come back and redo this)
Type in the new SBS 2008 server name, click check name and click okay.
And now we're ready for....
Uninstall Exchange 2003 or Exchange 2000 by using Add or Remove Programs from Control Panel. For more information, see How to Uninstall Exchange Server 2003 or How to Uninstall Exchange 2000 Server.
For this next step I'll need disk 2 of SBS 2003 or SBS 2003 R2.
And DON'T go in and remove the Exchange from where you think you need to remove Exchange, remove it from the SBS 2003 section. I need to download that media from TechNet plus to put it on that box. If you don't have access to your customer's media "any" SBS 2003 disk 2 media will do.
You must uninstall Exchange Server 2003 from the Source Server before you demote it. This removes all references in AD DS to Exchange Server on the Source Server. You must have your Windows Small Business Server 2003 media to remove Exchange Server 2003.
To remove Exchange Server 2003 from the Source Server, click Windows Small Business Server 2003 in Add or Remove Programs, and then click Remove. Follow the instructions to finish the procedure.
