Exchange server dependent on each other

My enviornment:

Exchange 2007 SP2 server (Hub, CAS, Mailbox roles)
Windows Server 2003 R2 SP2 (Secondary DC, Secondary DNS)

Exchange 2010 SP1 server (Hub, CAS, Mailbox roles)
Windows Server 2008 R2

I have recently introduced our Exchange 2010 to our environment with a few bumps along the way but all functions on the new server work without issue.   I've migrated mailboxes and (so far) no complaints from our users.

It is now time to take the old exchange server down so I decided that before I do that, I should disconnect the old server from the internet/intranet and verify that I can still receive emails.  As soon as I disconnect all copies of Outlook gave me a "disconnected" status even though the associated accounts are on the new server.

I know now I should have tested this before migrating but alas I didn't.  I'm beyond nervous to uninstall Exchange 2007 and demote the server.

Is it normal for the 2 servers to be dependent on one another that if one is disconnected they all are?  Or did this happen because the Exchange 2007 server also is a domain controller?

If they do rely on each other, will uninstalling affect the new server's ability to connect?

What problems will I theoretically be facing?  Should I start drinking now?

Any help would be greatly appreciated.

This indicates you are still using the HUB on 2003.
If you have a separate hub server, and it goes off-line, then messages get stuck in the outbox and will not move.

Thanks for the quick reply.  

I decided to try and narrow down what the 2010 server is dependent on.

I stopped ALL exchange services as opposed to just disconnecting the net.  I can still send and receive email's with no dis-connectivity to the 2010 server.  

Postmaster: is the Hub dependent on the transport service? Will stopping the service rule Exchange 2007 as the reason for disconnect?

My assumption is that AD is causing the disconnection which is still an issue.  Shouldn't the 2010 server be able to point to both our primary and secondary DC's?

DC's are used for authentication by Exchange. They do not control mail flow at all. The transport service does the moving of mail.

Ah ok.  

Strangely enough, I went and disconnected the net from the 2007 server and I did not loose connectivity to the new server.  I guess I lost connectivity coincidently.

With the 2007 server completely off the grid I can send/receive email and am actively connected to the server.  In theory I should be ok to uninstall Exchange 2007 and demote the server?  Are there any other checks I should do before uninstall and demote?

Thank you once again for your help!  I can soon sleep easy once the old server is put to rest.
