Anyone here ever done a Groupwise 8 -> Exchange conversion? I'm planning a migration to finally get off the horrible pile of poo poo that is Groupwise, and in doing so remove the last piece of Novell from our network. I've never touched Exchange from an admin perspective or server maintenance perspective before, so I'm learning from the ground up and doing a lot of reading. So far I've figured out how to make Exchange send emails that it can't find mailboxes for to the Groupwise server, but I haven't found a way to make Groupwise do the same. Worst case is I can have Outlook access the user's Groupwise account until everyone is migrated, but I'd love to be able to have something more elegant in place. Any tips for migrating would be greatly appreciated.

Last night I attempted to put a new hub transport and client access server in production with my Exchange 2007 infrastructure that I admin, and...it didn't go so well. My plan was to take the new server and give it the same IP as the old one. Both the new server and the old one are VMs so that was easy to do. I got our SSL cert installed. I removed the connectors from the old server. I got the new server up and running at the same IP, aaaand...no delivery. I just can't figure out why. It was set up as closely as I could get it to the old server, and it just sat there and didn't do JACK, even though it was the only active hub transport server in the organization. No errors related that I could find in the system logs. The only thing I can figure is that even though I disconnected the old server, it was still listed in the infrastructure. Could Exchange have been attempting to route mail through it in spite of being told to connect only with the new server?

Exchange 2007+ (and 2003 but who the gently caress uses that anymore ) can have multiple instances of servers living together in perfect harmony. Even 2010 can live together with 2003/2007, etc. Did you shut down the old VM first and then make this new one? If you want to "decommission" an old server, uninstall Exchange off it, and then remove that bitch from the domain. For something like this, I would install the new server(s), move everything to the new ones (while the old one(s) is still running) and then decommission the old one. That is just going on your post and not knowing much about the domain/etc.

I was specifically told not to completely decommission the old ones so that we would have a fallback option, or whatever. I don't know. In retrospect I'm glad I didn't touch them, because at least I could revert at 5 AM this morning after loving with it all night. The primary reason I went with the same IP is that it was the one set up for external mail communications (via NAT and DNS). I guess I was trying to make it as simple as possible so that none of that would have to be changed. Considering that the new hub transport/client access server was doing the exact same thing as the old one, I didn't think this would be a problem. We're going from this: 1 combined hub transport/client access server that is also running OWA (and it's too much for it), 1 mailbox server To this: 1 hub transport/client access server, 1 client access server dedicated to OWA, 1 mailbox server (the same one) There is some weird stuff going on, like the internal domain name being different than the external domain name, and the fact that they're both .com domains. I also ran into an issue since mail.$company.com pointed to the combo server before, and that's what people were using to get to OWA...I didn't know this beforehand, and then when I brought it up I was told I couldn't change it to, say, webmail.$company.com because "too many people use it." Whatever. We also have journaling set up going to a Barracuda. If I need to yank the old servers completely I can do that; if all else fails I can clone the most important one before I do it so that I can revert to the clone if needed. There's already two servers, including the original Exchange 2003 server, still listed in the infrastructure because they weren't properly removed. They don't seem to be causing problems, but I'm not 100% sure. I also have no idea how to get them out.

Gyshall gave the best advice you can get. When implementing new servers in an Exchange environment you want to install the new servers, configure the new servers, verify they're working, then uninstall Exchange from the old servers. Uninstalling Exchange is probably the most important part since it will take care of removing all references to the servers from active directory. Once the old servers are fully removed changing the IP address of the newly installed machine to match the old isn't too difficult.

They don't seem to be causing problems, but I'm not 100% sure. I also have no idea how to get them out. They can cause a problem depending on what information is out there in AD (for example you won't be able to install Exchange 2013 since there's still Exchange 2003 in the environment). I believe the best solution here is to install an Exchange 2003 server with the same name/role as the one that was orphaned and then perform an uninstall procedure.

For us it would be about $44k just for the licensing.

It is possible to remove the references in ADSI edit, but there's a lot of places you need to check, and I don't think I've seen them all documented in one place. Microsoft's recommendation is to install a server with the same information, so that when you uninstall it removes everything properly. Support article - http://support.microsoft.com/kb/833396 quote:Remove the Exchange Server 2003 server from Active Directory I had the same situation in my QA environment where someone removed a couple of my physical servers. I had to stand up a couple VMs to install/uninstall just to clean up AD Edit: Also be aware of any system folders in your public folder store that may have been replicated from a 2003 public folder store.

The best way to get rid of an old server like that is ADSIedit, then remove the server itself from the AD snapin, and then maybe ntdsutil metadata cleanup - I wouldn't mess with installing any more Exchange 2003 servers. Also, of consideration (if it is still an option), this is how we usually provision VMs for our clients where multiple Exchange servers are an option: 2 Hub Transport/Client Access Array servers (if high-availability is a factor) 2+ Mailbox Servers with Database Availability Groups (again, for high availability) 1 Edge Transport in the DMZ (if this is of consideration) Whatever old servers exist (some clients have needs for a legacy exchange server, for whatever reason.) We set up mail.domain.com to point at the Client Access Array, and then have legacy.domain.com point at the old Client Access (2003) stuff, both for internal and external. Also for what it is worth, you shouldn't have to do any nonsense with IP addresses when dealing with Exchange, outside of configuring a static IP on the server during install. DNS should be good enough for all that.

Where exactly do I need to be looking in ADSI for the old 2003 server? I'm also unsure of how to get mail.$company.com to point to the actual transport server as well as the OWA server. I won't be hosting OWA on the transport server at all. Am I going to have to set up a redirect?

ADSIEdit isn't a world of hurt unless you're not making daily AD backups, which you should be. Reinstalling/uninstalling sounds like a horrible idea, especially if the old server wasn't properly demoted/uninstalled. Powdered Toast Man, check out this knowledgebase article - http://support.microsoft.com/kb/833396 Here is what you're looking for in ADSIEdit: code:
Also, for your hub transport/OWA issue - what does your firewall situation look like? In this case you should probably set up a DNS pointer for smtp.domain.com or something to point at the transport server internally, and then mail.domain.com to point at the Client Access servers externally and internally, if that makes sense. On our outside firewalls we use NAT rules to do this, but there really isn't a need to open SMTP traffic directly on the outside. Also I'd run dcdiag tests on your Domain Controllers to make sure they're not referencing the old servers at all.

Does anyone here have a link to the proper way to create new users once you cutover to O365? I've been reading even more about the cutover process and once I get everything over to O365 w/SSO and DirSync, you have to convert your users to Mail Enabled Users (otherwise, once you decommission onpremesis exchange, you run into problems). From what I can tell, the only way to do this is to use the attribute editor in AD or I believe you can also use powershell? It's not the biggest of deals but it would be nice if there was a way to create a "New -> MEU" right out of the GUI. Is this possible?

Hmm. Poking around in ADSI...the old 2003 server is actually in its own administrative group, which does not contain the new servers or really anything else I can see. Would it be safe to just nuke the entire administrative group?

So you're advocating a method you have no idea would even work? Are you aware of how Exchange tracks servers (GUID, product IDs, etc) that your method probably would just make stuff worse? An Install/Reinstall masquerading as the old server sounds like a horrible idea. Honestly if you're doing any sort of Microsoft Active Directory or Exchange level administration, you should probably be familiar with ADSI Edit or NTDSUtil/etc. sanchez posted:Usually these old 2003 servers (especially SBS environments) are so screwed up it's practically required.

sanchez posted:The adsiedit route is fine, microsoft even has instructions http://support.microsoft.com/kb/833396 I may be reading this wrong, but in the article you (as well as Gyshall and myself have linked) in the section specifically about removing the server using ADSI Edit the article says this right above where you're getting your steps from quote:If you cannot install or run Exchange System Manager, you can use the Active Directory Service Interfaces (ADSI) Edit snap-in to manually remove enough of the server attributes so that you can try a successful reinstallation. This method does not perform cleanups of references to the server object outside the server's own container. We do not recommend that you use this method unless you intend to immediately reinstall the server in the same administrative group. This is because you may have to manually remove or edit many attributes on objects throughout Active Directory. I mean, sure you can go into the servers container and delete the server out of there and it will disappear from System Manager, but just deleting from the Servers container doesn't remove references to the server that exist outside of that container. Sure things will still work, but you may run into some odd problems with those old references hanging around in AD. Powdered Toast Man may run into these problems trying to install Exchange 2013, as it will find references to the Exchange 2003 environment in AD and the install could fail. As far as reinstalling/uninstalling servers, again according to the article all three of us are linking, they are saying that you should only do the ADSI Edit directly if you are going to be doing a reinstall/uninstall right afterwards, and if you are not they do not recommend deleting anything in ADSI Edit.

That should be enough to get the references out from AD for just the 2003 server, for all intents and purposes. I think I've had to do that before, even in 2003/2007/2010 environment where the old 2003 CAS got hit by a virus and wiped out all the IIS stuff. After deleting the server from ADSI Edit, I'd probably run the Exchange BPA a few times to make sure all was OK from that angle.

Also, instead of moving his public folder replicas (or upgrading anything correctly), he just shut down the 2003 server and formatted it once the mailboxes were moved. He also tried installing 2010 on Server 2012, hosed that up, and deleted that VM. When I told him that his public folders were gone forever, his response was basically "ah well, life goes on". I appreciate his Zen approach to loving up his entire organization. His AD environment was an even worse nightmare. That Server 2012/Exchange 2007 server was also the operations master for his domain. Once I created a 2008 R2 server with Exchange 2010 and moved all his mailboxes and mailflow, he deleted the VM running 2012/2007. That's about as much experience as I have with 2013 though.

I think it was me who mentioned 2003 public folder data. For that I would just assume it's not there and deal with it if it becomes a problem later. Where it could come from is when you are decommissioning a 2003 public folder store and you have to move all the replicas to another public folder store. If you replicate all of the NON_IPM_SUBTREE folders from the 2003 to the 2007/2010 public folder store then later when you try and install Exchange 2013 the install may fail due to the 2003 system public folders that are still in the org. It's not a likely scenario to run into so I would just keep going with what you're doing, but if it fails that's something to look at.
