Server relocation assistance.

[mycarsavw]

If I set this out logically, it should be easy for someone smarter than what I is, to assist.

I have two offices; Office 1 and Office 2.

Office 1 has an SBS 2011e server and a 2k3 WSUS server. Emails for our current domain are all hosted - this will not be changed.

Office 2 has an SBS 2008 server which is purely used as an Exchange server serving emails to an old domain.

Office 2 will shortly be sold.

I'd like to move the server from Office 2 to Office 1. I don't want it to have anything to do with Office 1's network at all.

In my head, I move it, make sure it is on a different IP range and voila, that's it, but I know little to nothing about Exchange.

Is this possible? Any gotchas I should be aware of before I get stuck in?

Thank you.

Can you not keep it on it's own switch and completely separate and firewalled off from your main network?

[mycarsavw]

That's what I was asking

You'll need to NAT it behind the same firewall, I guess. Have you got a spare external ip address for this?

Also: which Exchange services are you wanting to expose to the internets? SBS not my forte, but happy to help if I can.

[mycarsavw]

Blast, completely overlooked the external IP issue.

As for which Exchange services, does this help?

I can do SBS, what I can't do is Exchange, so I appreciate any help you can offer, thank you.

So... are you exposing only SMTP to the internets, or have you got OWA (ie webmail), Activesync and any other bits to consider? Bear in mind that you'll want to update the DNS and rDNS of the domain for the MX to the new IP address, as well as any other things like SPF if you have that in place.

If you've got the extra external address that's great - it's just a case of setting up firewall rules. If possible I'd be running this off a separate port on your firewall, with it's own switching but you technically could just do this with a different ip space. If going the latter I'd want to VLAN the networks off too.

[mycarsavw]

I'll admit I love to over complicate things, if only to give myself a project. Your comments about only needing certain services and updating DNS got me thinking.

All old-domain addresses are automatically forwarded to their new-domain counterparts. These are receive only boxes, all they're effectively doing is acting as a mail redirection service.

Activesync, OWA etc are no longer needed.

I'm currently using Office365 (Exchange Online 1) in Office 1.

The obvious solution would be to add the old-domain and host the emails?

Am I missing anything?

[Splash]

Right - so they're both handling mail for the same company, but one is the old domain? If so then yep - you could just add the old domain as an accepted domain in o365 (there will be some bits that you need to do there), repoint the MX for that domain and away you go. Only caveat would be if you have any SMTP addresses that don't have equivalents in the new domain, so you'd need to manually assign those to a mailbox (else when email reaches o365 it'll be bounced as the mailbox doesn't exist.)

[mycarsavw]

Edit: Yep, two companies merged to form one. Two domains ceased, one new one was created (mail handled by O365). One domain currently has paid for hosted mail (which will now cease because I'll add that domain to O365 too), t'other has the server above.

So simple. Unlike my thought processes.

I presume, as each machine has already retrieved and saved local copies of all emails, turning the server off once the domain has been added won't have any ill effects?

Appreciate the assistance and apologies for going the long way round.

erm... when you say that are you referring to the clients of domain2? Exchange is a server-side thing, so you'd want to either export the mailboxes (you can do this to PST using Powershell if needs be) and then import to the mailboxes in o365, or accept that once the server goes offline then the mail/calendar/etc is unavailable.

(feel free to drop me a PM and we can continue by email if you'd prefer, not sure how much of this will be useful to the rest of the forum )

Thanks to Splash this one is resolved.

A true gentleman.

Happy to help - glad you got it sorted (and learned some stuff that may or may not be useful at a later point!)
